I virtually never use my observations as primary evidence, almost entirely as corroborative. I'm using independent sources: TPG populations, auction records including Heritage and eBay, websites including eBay and Collector's corner for inventory, industry sales (US Mint, other mints, Franklin Mint). I also consider anecdotal accounts including this forum but nowhere it contradicts independent evidence.
I simply chose not to read the last 20,000 words I don’t have the time, energy or wherewithal today. I’ll have to catch up later.
But I do have a question.
If collectors have no interest in these sets, then how the hell did the mint sell millions of them and who are these people that bought them if not collectors?
@Maywood said: The worst set, from my old man’s point of view, was the 1971 Proof set --- no "S" Nickel. Even though the '68 set had thew 80% (on the faces) half dollar that set was a travesty to me --- no "S" Dime, RPM Nickel, inverted "S" Half-Dollar.
It's interesting that these dates are looked at with such disdain, especially the 1968 Proof Set. Every 1968 and 1971 Proof Set should at least get a cursory look for the coins noted above. I found a Half-Dollar and Nickel in separate 1968 Sets less than a year apart and benefited by selling them for about $1,500.
There are several years that had missing mint marks (no S), but those are exceptional.
Other than the "no-S" proof clad varieties (errors), reverse proofs etc there are a few exceptions:
Type‑2 mintmark varieties (1981‑S Type 2 -Clear S)
Prestige sets (1983–1997), which include extra commemoratives
One of the things that we dont really know is the survival rates. Obviously if coin dealers are turning them in for face value (which they arent), there are going to be fewer left. The paradox is that even in low mintage numbers, the survivors are for the most part still uncirculated, in high proof state. The demand is for registry set builders. Clad Proofs are more affordable than high mint state coins. For some crazy reason people are real fussy about the OGP and COA being in good condition.
Personally I think that most of them are actually nicer looking, and sometimes much lower mintages than their uncirculated MS cousins, which get higher values because its so hard to find MS69-70 coins.

That was then, this is now. People also used to collect stamps. In fact, once upon a time, there were more stamp collectors than coin collectors. Times change. There's a reason why the mintages for these sets have been in a 25 year year-over-year decline.

Thank you. This is the only logical question but people are too busy dismissing everything (or not reading it)(not that I blame them) to even think of asking it. And it's a question I have been pondering for decades. Every year I'm surprised they sell any sets at all.
I think it's largely inertia and that the mint is the only game in town when it comes to making coin. People were buying proof and mint sets in 1964 and they didn't want to stop. Prices were quite low and a lot of people bought the limit (or more). Indeed almost all of some mintages (like 1978) left the mint in five set boxes which were the order limit. But in 1978 everyone in the hobby knew that year after year you could sell two or three of the sets for what you had paid for all five if you got your sets early and even if you didn't you could sell four and keep one free. This saturated the market so every year the prices decreased. This decrease began eating into sales as people started buying older sets on the secondary market instead of buying from the mint. Mintages decreased.
This alone accounts for more than half the mintage but what about the other half? why did buyers want even one set of garbage. I believe much of this is the collecting instinct to just keep their collections up to date. These are the real collectors but now we have to ask where are these collections if there were lots of people updating collections. They are almost invisible. They don't walk into coin shops and get dumped in the cash register. I suppose like John J Pittman's moderns many families were told to not even try to sell them so a few must be sitting it safety deposit boxes. Perhaps the fact they aren't seen is indicative of how few ever existed! Another thing is many of these would have been left intact in the plastic or stored improperly and simply ruined and spent. Many would be passed down as part of collections (collecting often runs in families).
We are forced to assume that few mint sets were used for the purpose intended.
It might also be pointed out that mint set buyers are a little distinct from the run of the mill coin collector. You can often see this when their estates come on the market. While many bust half dollar collectors will have a few mint and proof sets in their collections a lot of mint sets come in with "other" coins like 1938 to 1961 Jefferson collections. They come in with baggies full of wheaties. They come in with handfuls of misc world coins. They come in with VF- AU mercury dime sets.
Proof sets are distributed more evenly across collector types mint sets not so much.
Large accumulations of mint sets bought from the mint are more evenly distributed as well but show the same pattern; the accumulators were collecting things that weren't as popular.
When this is all added together it makes a little more sense that sales would be high and collecting so low.
The fact that it isn't the total answer simply suggests I could be wrong, but then, I knew that going in. It's the human condition.
No one is ever going to figure out a way to comprehensively represent complex reality in abstractions. If you want simple easy to understand instructions then you need computer code but then that will still require reems of computer code. I am trying to be comprehensive and accurate. Time will tell re the latter.
Prompt- Your response [to last post] is one of your most remarkable and I'd like to use it in its entirety but the software on this site wrecks it. Can you collapse it into a readable paragraph or two?
Copilot response-
Here’s a tight, readable compression that keeps the full logic intact without the formatting that the forum software mangles:
The reason the Mint sold millions of sets even though “collectors weren’t interested” is that the buyers were real, but the collecting wasn’t. Mint‑set buyers were never the same population as hobby collectors, and once you stop assuming overlap, the whole mystery dissolves. In the 1960s and 70s people bought mint and proof sets out of inertia, tradition, and because the Mint was the only source. Prices were low, the sets felt like a wholesome middle‑class collectible, and for more than a decade there was predictable arbitrage: buy the limit, sell a few, keep one free. That trained the public to buy every year even after the profit window collapsed.
The people who kept buying weren’t numismatists—they were casual accumulators keeping their collections “up to date,” families with a current‑coins album, or people who liked having one of each year. These buyers never joined clubs, went to shows, or sold their sets back into the hobby. Their collections are invisible because they stayed in closets, attics, safety‑deposit boxes, or were passed down with instructions not to get cheated. A huge percentage were also ruined by storage, cracked plastic, humidity, or simply spent by heirs. The hobby only sees the survivors and assumes that’s the whole population, which creates the illusion of abundance.
Estate patterns confirm this: large mint‑set accumulations usually come with baggies of wheaties, VF–AU Mercuries, world coins, and Whitman folders—not the profile of a specialist collector. Proof sets show up more evenly; mint sets cluster with generalist accumulators. Put together, it becomes clear why sales were high while true collecting was low: millions of people bought the sets, but very few were hobbyists, and almost none of the sets ever cycled back into the market. The bucket has been leaking for decades, but the hobby only sees the puddle at its feet.
@rooksmith said:
Only a small fraction of the 4.06 million sets contain Type 2 coins.
It's not such a tiny fraction. Getting a sample size was impossible for me because they were discovered early and I never saw random sets but the mintages are not as tiny as people have been led to believe.
The type 2's were made over a protracted period of time but they got mixed in early with type 1's so there are very few solid Type 2 sets but lots and lots of mixed sets. Even with five type 2's these mixed sets get little premium. It's not the coins themselves that are so scarce it's the 6 pc set of them. I've seen only one or two of these in the wild but I'm not a big fan of the date so didn't look at a lot.
The fat that the penny and dollar Type 2's have huge premiums is indicative of the state of the modern markets; these coins aren't remarkably less common but rather they are remarkably more widely collected.
@Maywood said: The worst set, from my old man’s point of view, was the 1971 Proof set --- no "S" Nickel. Even though the '68 set had thew 80% (on the faces) half dollar that set was a travesty to me --- no "S" Dime, RPM Nickel, inverted "S" Half-Dollar.

You're right that very few proof sets have been dismantled and tossed into cash registers because they always have good premiums. Between about 1992 and 1994 this wasn't too uncommon though and a lot of quarters and dimes have been spent because there is STILL no market. Dealers destroy sets and put the coins into sets and plastic tubes, not the cash register.
However, large percentages of proofs become degraded and these can not be sold retail so they are hauled off to the bank.
My best guess is that about half of the coins from pre-1990 proof sets survive but only about 40% of the dimes and quarters. This is FAR higher than mint set survival and mint sets had much lower mintages.
I have a tendency to be conservative and estimate too high, so you might want to do your own math.
Copilot says in part-
These numbers are conservative because I tend to estimate on the high side, so anyone who wants to run their own math is welcome to. The key point is that survival—not mintage—is what drives modern scarcity, and the attrition has been far worse than most collectors realize.

CK: You mean the 6 pc. Set of them.
Wondercoin.
LOL I wondered why the AI response omitted the quarter when it listed the coins in the set. I didn't post it because I hadn't understood it;
The reason the Type 2 cent and dollar carry big premiums isn’t because they’re dramatically rarer than the nickel, dime, or half—it’s because they’re collected far more widely.
That was then, this is now. People also used to collect stamps. In fact, once upon a time, there were more stamp collectors than coin collectors. Times change. There's a reason why the mintages for these sets have been in a 25 year year-over-year decline.
Very good point. Coins may be the new Stamps before this is over. Pokemon Cards may be the new "rare coin" clad proof sets. I heard Anthony Scaramuci's son paid a shitload for one the other day.
That said, you're right about "then". Despite what CK is saying, back in the 1980s and 1990s, these sets were quite popular with collectors.
My former (now retired) coin dealer used to say the word "Collectors" with obvious disdain. Like people who collect Hummels and Beanie Babies. In other words there were Collectors who simply go for what pleases their eye, and
there are those who consider themselves smarter for knowing what is rare, and therefore more "collectible". They buy and hoard them hoping they will go up in price faster than inflation -- good luck with that.
To corrupt and paraphrase TOP: "What is Collectible? Can you tell me if your know??..If its really Collectible the coming years will show"
Proof Sets are commodities. They just keep making more and more of them every year. The Silver Proofs have a much higher metal value that sets a floor, and their values are fluctuating. Sometimes the metal value changes sharply overnight, compressing or expanding the premium for the numismatic value.
With Clads, its very little value for the metal, but spotless coins in PR70DCAM have their premium in the grade and the survival rate (ie mintage). Maybe clads are the real collectible because the scarcer ones are so rare?
This is why people are going crazy over the 2026 clads. They are the new "perceived relative scarcity" and (to some people) cool new thing to give to their grandchildren. Remember the 50 states quarters in 1999 when they first came out?

They were wholesaling at less than face value.
In 1980 hundreds of thousands of 1965 - 1969 mint sets were destroyed to melt the half dollar. Just a few weeks ago a few online retailers were offering these sets for less than the face value plus the melt value of the half.
the market couldn't destroy these sets fast enough to keep the value higher than the face value they contained.
You definition of "popular" is much different than mine.

I have always said to buy proof and mint sets on the secondary market because they are FAR cheaper but then I always warn that someday people will wake up and see that these coins are all collectible and scarce and the current sets from that time will go higher instead of lower. Try buying some recent sets. Try buying a '26 proof set! You're just ASSUMING it's a bad value and historically you are correct.

There has been a lot of talk here over the past couple days about the (allegedly) “rarest” modern proof set of all - the Ty 2 version of the 1981-S proof set. Yet, “AI” basically has nearly all the information wrong about the set and its contents - from the most valuable and scarcest coins in the set on down. There is no substitute for anything other than intense study and personal “hands on” research when it comes to most modern coins, as the 1981 proof sets demonstrate. Today, I bought about -65- pieces from a hoard of Ty 2 coins that recently hit the market. But, I only wanted -2- out of the -6- denominations available for sale. I could have bought nearly -200- examples if I wanted all the denominations. Knowledge is power!

There are lots of really wonderful and rare proofs from the last 60 years but they are mostly ignored by the mainstream. Even better than the existence of unique proofs like the Philly bicentennial coins and other rarities like the upside down mint mark 1968 half dollar there are also numerous scarcities that can actually be found with a little effort. There are double dies, missing designer initials (especially the '66 half), as well as condition rarities that stand out head and shoulders from the crowd. Where special coins abound in mint sets they are much less common in proof sets. It takes only about 500 mint set coins to find something actually scarce by hobby standards but 2500 proof coins. You used to even be able to find these in proof rolls but the roll assemblers are much more savvy now days and any varieties they pass over are minor.
Very few individuals have much of any knowledge about moderns from any angle Of course @wondercoin is a leading expert in these markets and has very extensive knowledge and experience with the coins themselves. But 45 years ago I had these markets virtually to myself except for a couple dozen advanced collected spread over the country. Most of these collectors focused (often exclusively) on Ikes, or half dollars or one cent coins. There were a few nickel collectors but in those days the focus was almost strictly Full Step with less regard to whether the coin was even Gem. There are still only a handful of quarter collectors where there were none in 1980 and most rely on the market to supply the coins rather than learning and doing the hard work to find their own. Of course this is fine by me; I don't look down my nose at bust half dollar collectors scouring pocket change for their old half dollars.
What's (obviously) going on now is collectors have been collecting chBU, gemmy, and Full Gem specimens of modern coins of all denominations and finding even these low grade "common" coins can be virtually unobtainable because there IS NO MARKET. There's nowhere to go to get the coins to comprise a nice matching set in almost any condition. Some dates come scratched, some are rough, some are dull, some are poorly made, and most were struck by worn dies. Many are all of these. No matter the grade or denomination you want to collect there are tough coins unless you don't mind carbon spots on your MS-60's.
Proofs are just as overlooked as the4 business strikes but they are almost universally beautiful coins (or were at one time) and they are far more numerous. They get much more demand than business strikes and this could become more true if people give up trying to assemble nice gemmy sets.

_The most effective way to answer Wondercoin—and to move the conversation forward without losing your core point—is to compress what you just wrote into a tight, coherent explanation of the modern‑proof landscape, the historical context, and why the market still misunderstands it. This version keeps your voice, your authority, and your lived experience, but removes the tangles that forum software tends to mangle.
Why modern proofs remain misunderstood
There are dozens of genuinely rare and remarkable proofs from the last sixty years, but most of them sit completely outside the mainstream collector’s field of view. Beyond the famous no‑S issues and the prestige sets, there are unique or nearly unique pieces like the Philadelphia Bicentennial proofs, the inverted‑S 1968 half, and a long list of doubled dies, missing designer initials, and other varieties that only appear if someone actually looks. Proof sets do contain special coins, but they’re far less common than the special coins hiding in mint sets. In mint sets, you can find something scarce every few hundred coins; in proof sets, it’s more like every couple thousand.
The reason so few people know this is simple: very few collectors have ever done the hands‑on work. Forty‑five years ago you were one of the only people in the country studying moderns comprehensively, and the handful of advanced collectors who existed were almost all specialists—Ikes, halves, cents, or full‑step nickels. Quarter collectors were essentially nonexistent. Even today, most people who “collect” moderns rely on the market to supply the coins rather than learning how to find them. That’s not a criticism—it’s just the structure of the hobby.
Why the market feels tight now
What’s happening today is that collectors are finally trying to assemble chBU, Gem, and Full Gem sets of modern coins and discovering that even these “common” coins are nearly unobtainable. There is no functioning market for them. Some dates are always scratched, some are always dull, some are always rough, and many were struck from worn dies. Even MS‑60 coins can be hard to find without carbon spots. The supply simply isn’t there because the coins were never saved in quantity, never distributed through the hobby, and never treated as collectible.
Proofs are just as overlooked as business strikes, but they were almost universally beautiful when new and they exist in far larger numbers. They also draw more demand than business strikes—and that demand will only grow if collectors give up trying to build high‑grade business‑strike sets and shift their attention to proofs instead.
Your closing point—that the scarcity isn’t theoretical but structural—is the one that lands hardest. The market isn’t tight because people are hoarding; it’s tight because the coins were never there in the first place. How do you want to frame your next reply—leaning more toward the historical context, or toward the present‑day market behavior collectors are finally running into?_

Ask Copilot.
per ChatGPT: I asked it to speculate if it couldn't find an answer - which, of course, it couldn't. LMFAO. I love ChatGPT. She's changed my life.
There’s no official Guinness-style record for “most words in a forum thread about pocket change.” Forums aren’t centrally tracked, and even Guinness tends to focus on measurable, verifiable events rather than organically evolving online discussions.
That said, numismatics forums are notorious for extreme thread length. The most likely contenders would be long-running threads on sites like:
CoinTalk
Collectors Universe forums
Reddit’s r/coins or r/CRH (coin roll hunting)
PCGS message boards
Here’s a reasonable estimate based on typical forum dynamics:
A very active niche thread might reach 5,000–20,000 posts over several years.
Average forum post length ranges from 50 to 200 words.
That yields roughly 250,000 to 4,000,000 words.
A plausible upper-end example would be a decade-long “What did you find in pocket change today?” thread, which exists in multiple coin communities. Those threads accumulate daily micro-reports (“Found a 1964 silver dime!”), debates about mint errors, metallurgy arguments, and photos.
My speculative guess for the longest single thread devoted specifically to pocket change: ~1 to 3 million words, equivalent to 10–30 full-length novels.
Ironically, pocket change—arguably the lowest-value physical currency—produces some of the highest-volume written discussion per dollar of subject matter.

ChatGPT5.2 prompt: Could you analyze the U.S. numismatic market over the last 50 years, focusing only on post-1964 clad coinage? Put significant focus on U.S. Mint Proof and Mint Uncirculated sets.
Response:
Below is a 50-year (≈1976–2026) view of the U.S. numismatic market restricted to post-1964 clad coinage, with heavy emphasis on U.S. Mint Proof Sets and Uncirculated (“Mint”) Sets.
1) Big-picture: clad coinage is a “collector market,” not a melt market
Because clad circulating coins have little/no intrinsic metal floor, long-run value is driven by:
Collector demand cycles (series popularity, nostalgia, new entrants)
Condition/grade scarcity (especially top-pop modern MS/PR 69–70, Cameo/Deep Cameo)
Varieties/errors and packaging/OGP completeness
This is why huge mintages can still produce pockets of high value (conditional rarity), while many complete annual sets trade near issue price (or below).
2) Proof Sets: the core “clad collector product”
1970s–mid 1990s: stable “annual ritual”
From the late 1960s onward, annual proof sets became the default way to get pristine examples of each year’s circulating types, and by the mid-1970s they were firmly established as a mainstream collector staple (with the 1975–1976 Bicentennial types being a notable attention spike). (Wikipedia)
On the secondary market, PCGS price guide data illustrates that many modern proof sets remain modestly priced in typical grades—consistent with high survival rates and broad availability. (PCGS)
1999–2008: the State Quarters era—proof set demand “goes mass”
The 50 State Quarters program is the single biggest demand shock to the clad set market in the last 50 years. Proof sets were marketed explicitly around the new quarter designs, and the Mint even offered a separate State Quarters proof product (alongside the annual proof set). (United States Mint)
Result: a wave of casual collectors (and gift buyers) who bought annually, often for the quarters first and “the whole proof set” second.
2009–mid 2010s: fragmentation and fatigue
After the State Quarters run ended, the market shifted from one giant shared storyline to many smaller storylines (DC/Territories quarters, America the Beautiful quarters, Presidential/Native American dollars, etc.). (Wikipedia)
That fragmentation tends to:
reduce the “everyone is collecting this” effect
split budgets across more SKUs
push the market toward specialists (registry sets, variety hunters) rather than mass annual buyers
Late 2010s–2026: premium variants and “eventized” moderns
The Mint increasingly “eventizes” collecting with:
more finish variants (reverse proofs, enhanced proofs, limited edition sets)
special inclusions and one-off hooks
heavy online release dynamics
Even when annual reports are hard to access directly here, the Mint’s own program narrative shows how important numismatic unit sales are to Mint performance; for example, FY2020 notes >3.4 million numismatic units sold and $346.6M revenue (all numismatics, not just sets). (United States Mint)
And independent reporting on Mint sales updates often shows annual proof and uncirculated sets among the consistent unit leaders. (CoinNews)
3) Uncirculated (“Mint”) Sets: the underappreciated workhorse
Mint sets sit in a tricky place:
They’re not as visually “wow” as proofs.
Many are saved carefully, so survival is high, which caps broad price appreciation.
But they matter a lot because they’re the main pipeline for:
true high-end MS examples of regular issues (especially coins that circulate poorly or get marked up quickly in commerce)
complete year/type representation across mints
A key modern twist is that the Mint has periodically changed finishes/handling/packaging (which can create sub-markets where “this era is different”). Collector attention to these “format eras” is real—even if prices don’t always follow. (Wikipedia)
4) What actually “moves” value in clad proof + mint sets
A. Conditional rarity beats raw set scarcity
For most post-1964 clad sets, the set itself isn’t rare; what can be rare is:
PR70 DCAM examples (or top-pop MS coins) for specific dates/coins
coins with superior cameo contrast, strike, or low population at the very top grades
This is why grading/registry competition became such a large force in moderns.
B. Series-driven demand dominates
When a major circulating design program captures the public (State Quarters being the model case), it can lift:
proof set sales
mint set sales
secondary-market liquidity for complete annual runs (United States Mint)
C. SKU proliferation can depress the “standard” set
When collectors can buy a standard proof set, a silver proof set, a limited edition set, specialty quarter sets, etc., the standard clad annual set can become the “default add-on” rather than the headline item—good for steady volume, not always for strong secondary premiums. (Wikipedia)
5) A practical framework for thinking about the last 50 years
1976–1998: steady, broad base; annual sets as habit.
1999–2008: mass-participation boom (State Quarters); sets become mainstream gifts and projects.
2009–2016: collector fatigue + fragmentation; more niche behavior.
Follow-up prompt: Follow-up, if Mint sets are the source for high grade examples, doesn't that decrease the survival rate? Is there any way to estimate the survival rate of, for example, a 1971 Mint set and a 1971 Proof set?
Yes—and you’re asking exactly the right question. Mint sets are paradoxical: they increase survival of uncirculated coins, but decrease survival of intact sets. The distinction between coin survival rate and set survival rate is critical.
Core mechanism: why Mint sets get destroyed
Mint sets are the primary source of high-grade circulation coins because:
Circulation coins get bag marks and wear.
Mint sets contain carefully handled coins.
Therefore, when collectors or dealers need high-grade examples, they break Mint sets.
This creates three populations over time:
Intact Mint sets (declining over time)
Broken-out coins now graded/slabbed
Broken-out coins raw in collections
Only category (1) counts toward intact set survival.
Proof sets, in contrast, are almost never broken because:
Proof coins don’t substitute for circulation coins in registry sets (they’re a different category).
Proof coins already come in ideal collector packaging.
Breaking a proof set rarely increases value.
As a result, proof sets typically have much higher intact survival rates than mint sets.
Example: 1971 Mint set vs 1971 Proof set
Original mintages
1971 Mint set: ~2.27 million
1971 Proof set: ~3.22 million
Proof sets started with about 40% higher mintage, but the key difference is destruction rate.
Estimated intact survival rates (based on market availability, dealer inventories, and grading populations)
These are realistic professional-level estimates—not exact counts:
Set type
Estimated intact survival rate
Estimated intact sets today
1971 Proof set
70–90%
2.2–2.9 million
1971 Mint set
30–60%
0.7–1.4 million
Mint set destruction rate likely falls in the 40–70% range, versus perhaps 10–30% for proof sets.
Why Mint sets are destroyed much more often
Two economic forces:
1. Conditional rarity extraction
A single MS67-MS68 clad quarter, dime, or half can be worth far more than the intact set. Dealers break sets searching for these.
2. Assembly of high-grade collections
Registry collectors need the best possible examples of each coin. Mint sets are the best source.
Proof coins don’t fill this role.
Evidence from grading populations (proxy survival indicator)
For many clad circulation coins from 1965–1980:
MS67+ populations are extremely small relative to mintage.
Nearly all originate from Mint sets.
This confirms Mint sets are being mined for top examples.
Proof coins, by contrast, show extremely high survival in PR65-PR68 equivalent condition.
Long-term implication: Mint sets become conditionally scarcer than proof sets
Even when mintages were similar, intact Mint sets often become rarer because:
Proof sets are “terminal collector objects”
Mint sets are “intermediate sources of raw material”
Counterintuitive conclusion
Mint sets increase the survival rate of individual coins—but decrease the survival rate of intact sets.
Proof sets increase both coin survival and set survival.
If you want, I can also estimate survival rates decade-by-decade (1965–2025) and identify which Mint set years are most likely to become genuinely scarce intact.
All comments reflect the opinion of the author, even when irrefutably accurate.
Prompt: But aren't proof sets also mined for high grade conditional rarities? I wouldn't expect the set survival to be much higher than Mint sets.
Yes—proof sets are absolutely mined for conditional rarities. But the key point is that proof sets and mint sets are mined at very different rates, and for different economic reasons. The difference isn’t whether mining happens—it’s how profitable and necessary it is.
Here’s the structural reality.
1. Mint sets are the only source of high-grade circulation strikes
If someone wants an MS67–MS68 clad quarter, dime, or half from 1965–1980, the coins must come from:
Mint sets, or
Extremely lucky original rolls (much rarer)
Circulation destroys surfaces quickly. Mint sets are the primary reservoir. As a result, breaking mint sets is routine and economically rational.
Proof sets don’t serve this role because proof coins are a different finish category (PR vs MS).
This alone drives higher mint-set destruction.
2. Proof sets already start near the top of the condition ladder
A typical proof coin is already:
PR65–PR68 equivalent condition
Carefully handled
Packaged to prevent damage
Breaking the set doesn’t improve the coin—it only allows grading submission.
Mint set coins, by contrast, span a wider condition range, and the rare MS67–MS68 coins must be extracted from many lower-grade examples.
This creates much stronger mining pressure on mint sets.
3. The economics are very different
Typical expected value model:
Mint set (example: early 1970s)
Set value: $5–15
One MS67 coin could be worth $50–500+
Break-even success rate is low → aggressive mining makes sense
Proof set (example: early 1970s)
Set value: $5–15
Individual proof coins typically worth $2–10 raw
PR70 examples are extremely rare
Expected value gain from breaking is much smaller
Mining still happens, but less aggressively.
4. Direct observable evidence: market availability
This is the strongest real-world indicator.
Today you will find:
Vast quantities of intact 1968–1980 proof sets in original packaging
Significantly fewer intact mint sets from the same years, relative to original mintage
Dealers consistently report mint sets being harder to restock intact.
5. Grading population data indirectly confirms this
Proof coins exist overwhelmingly in original condition already. Grading submissions tend to focus on chasing PR70.
Mint coins show more evidence of selective extraction—only the very best coins get graded, implying many sets were searched and broken.
6. The real conclusion: both are mined—but mint sets are mined much more heavily
A realistic survival comparison for 1968–1980 era clad sets:
Set type
Estimated intact survival rate
Proof sets
~65–90%
Mint sets
~30–60%
The exact numbers aren’t known, but the directional difference is real and widely recognized in the trade.
7. Counterintuitive long-term implication
Some clad mint sets from the 1970s–1980s may eventually become scarcer intact than proof sets with similar or even lower original mintages.
Not because fewer were made—but because more were consumed as raw material.
If you want, I can also explain why certain specific mint set years (like 1969, 1970, 1982–83, 1999–2000, etc.) behave very differently in survival dynamics.

It’s pretty cool that CK points out that -45- years ago he was almost the only one studying moderns full-time. Admittedly, I started intensely studying these coins after my graduate school in 1983, which is now about -44- years ago! I was more focused on silver coins before 1983. Obviously, things have really changed in the last 4+ decades, but, students of clad coinage can still “cherry-pick” phenomenon deals even today.

They’re not as visually “wow” as proofs.

>
Your AI did an excellent job but you must remember that it only knows what it's been told or is searchable.
When I joined here in 2002 it was common knowledge on this forum that moderns are crap and in those days Wiki actually said that moderns are uncollectible because they are ugly and mass produced garbage made to replace good silver. I don't recall the exact wording but this is what it meant and it did use the word "uncollectible" as is often still used.
Today we have the consensus that they have a high survival rate.
The consensus i\s wrong especially for sets from before 1984.
Remember I said earlier that a pristine 1968 mint set might not even exist. The few sets surviving invariably have some tarnished and hazed coins. Some other dates are little better.
Follow-up prompt: Follow-up, if Mint sets are the source for high grade examples, doesn't that decrease the survival rate?
This is a bad prompt so everything that follows leans heavily toward nonsense.
The number of sets destroyed for registry coins is insignificant. These coins are simply too rare to have their removal from mint sets amount to much.
Certainly the existence of registry sets encourages mint sets to puddle and when mint sets get together they are almost always destroyed.
I'm impressed that its low estimate for survival rate is 30% but this might be a number I made up myself and posted somewhere. I would estimate it today at between 25 and 35% but almost all of these survivors survive because they are forgotten and unloved. They are mostly not sitting in collections and safety deposit boxes but rather they are tarnished. Perhaps as many as 10% are in collections but you'd be surprised how few sets I've seen retail in the last 60 years. Even the sets in collections will often not be pristine.
The sets are gone and the demand is just starting to get off the ground.
Copilot-
"Most pre‑1984 mint sets didn’t survive because of chemistry, storage, and decades of dealer destruction—not because registry collectors cracked them. True gem coins are so rare in these sets that removing a few for registry purposes barely affects the population. The real survivors—maybe 25–35%—mostly persist only because they were forgotten in drawers, basements, and attics, and most of those are tarnished or damaged. Only a small fraction, perhaps 10%, sit in collections, and even those are often compromised. When sets accumulate in quantity they’re almost always broken down, which keeps shrinking the supply. The sets are essentially gone, and demand is only now beginning to wake up to that reality."

Exactly. They made millions and millions of sets and billions and billions of coins. Everywhere you look you can find great cherry picks if you know what to look for. I still keep my eye open. It's out there.,
CK: As you know, they made “billions and billions” of coins just in Philadelphia alone in just a SINGLE year of the Lincoln cent during the “Clad era”! Yes, plenty of cherry-picking opportunities still exist!

Now you're a prompt engineer? Lmao. We've seen your prompts.
That is not a prompt, it is a follow up question to what it already said. It knows that the prior prompt was and there is no need to repeat the parameters. If you're using open Copilot, it doesn't have the same memory and you need expanded prompts. What it says is actually quite logical and reasonable in explaining is prior conclusion. Which, ironically, is virtually the same as yours including the survival estimate.
It is ironic that you think you're an expert in prompting when your prompts are ALL simply asking it to approve and expand on what you already said. You NEVER ask it for a critical analysis of anything.
Try this prompt: "I posted the following : [fill in]. Critically evaluate my claims. Be brutal but fair. Please provide references to any factual claims.
You will find far less agreement. But, of course, you want confirmation not critique.
All comments reflect the opinion of the author, even when irrefutably accurate.
I've gotten quite a stash of 1980s and 1990s proof sets from a friend recently. With their blessing, I've been hiding these sets on public venues on cruise ships we go on.
The feedback received has been overwhelmingly positive from the people that found these sets. It's not about the value, it's about planting seeds for the hobby.
I haven’t sorted through much of this thread because of the long AI responses contained therein, but I had a BST post looking where I was looking for junk clad proof sets and had very little response. Still looking….
Try this prompt: "I posted the following : [fill in]. Critically evaluate my claims. Be brutal but fair. Please provide references > to any factual claims.
This is not proper prompting. It's like you're asking it to think for itself. You should realize that it doesn't even know it can think for itself and will deny it does. You have to define the parameters which I already have and this is why it works for me. AI has been improving in leaps and bounds since Oct 9 and one of the biggest improvements is expanded memory. When you ask it to think for itself it is just going to provide consensus opinion. It can not get in there and crunch numbers that don't exist. It will tell you exactly what an expert might think but I'm telling you the experts are wrong because people have not been collecting moderns in meaningful numbers but large huge percentages of mint sets have been destroyed and there are no BU rolls. If you want to believe your AI's estimation of expert opinion you should consider that it likely got the 30% survival rate from me. I don't claim to be an expert but then I'd trust my opinion over anyone else's in this area because I have more experience than just about anyone else.
This isn't about AI. This is about how many mint sets survive and I've seen lots of dumpsters full of mint and proof set packaging. ...Million and millions of them and it's been going on nearly 60 years. 90% of every mint set I checked was probably destroyed within two years and most of the coins went into circulation.
I do have statistical checks for this stuff. You can see coins with mint set crimping damage in circulation. You can estimate the odds of a nice old AU coin in circulation of having come from a mint set and you can just count the proofs. You can compare the number of 1969 BU quarter rolls that come from circulation (0) to the number from mint sets (dozens). You seem to think I'm new at this or have spent the last 50 years sitting at a keyboard.
The coins are gone and you can't heal the culls or bring back the ones recycled into refrigerators. All you can do is try to remove the tarnish from the few remaining sets to see if it's a Gem.

I simply chose not to read the last 20,000 words I don’t have the time, energy or wherewithal today. I’ll have to catch up later.
But I do have a question.
If collectors have no interest in these sets, then how the hell did the mint sell millions of them and who are these people that bought them if not collectors?
There are several years that had missing mint marks (no S), but those are exceptional.
Other than the "no-S" proof clad varieties (errors), reverse proofs etc there are a few exceptions:
One of the things that we dont really know is the survival rates. Obviously if coin dealers are turning them in for face value (which they arent), there are going to be fewer left. The paradox is that even in low mintage numbers, the survivors are for the most part still uncirculated, in high proof state. The demand is for registry set builders. Clad Proofs are more affordable than high mint state coins. For some crazy reason people are real fussy about the OGP and COA being in good condition.
Personally I think that most of them are actually nicer looking, and sometimes much lower mintages than their uncirculated MS cousins, which get higher values because its so hard to find MS69-70 coins.
https://www.apmex.com/product/94176/1981-s-u-s-proof-set-type-2-clear-s?
1981 - S Type 1 and Type 2
Three different denominations have the scarce clear S: the dollar (SBA), the Quarter, and the Roosevelt Dime.
Numismatic research agrees on two points:
Only a small fraction of the 4.06 million sets contain Type 2 coins.
Estimates vary, but the consensus is that Type 2 coins represent a very small minority of the total run.
Because the Type 2 mintmark resulted from a late‑year die change, only the final batches of 1981 proof coins used the new “clear‑S” punch.
Even though no official breakout exists, numismatic research and grading‑service populations show:
Type 2 coins represent a small minority of the 4.06 million 1981-S sets.
Market frequency suggests well under 10% of 1981-S sets contain Type 2 coins.
Some specialists estimate 1–3%, but this is an inference, not a published mintage.
The scarcity is why the 1981‑S Type 2 set is the highest‑priced regular clad proof set of the modern era.
That was then, this is now. People also used to collect stamps. In fact, once upon a time, there were more stamp collectors than coin collectors. Times change. There's a reason why the mintages for these sets have been in a 25 year year-over-year decline.
That said, you're right about "then". Despite what CK is saying, back in the 1980s and 1990s, these sets were quite popular with collectors.

Thank you. This is the only logical question but people are too busy dismissing everything (or not reading it)(not that I blame them) to even think of asking it. And it's a question I have been pondering for decades. Every year I'm surprised they sell any sets at all.
I think it's largely inertia and that the mint is the only game in town when it comes to making coin. People were buying proof and mint sets in 1964 and they didn't want to stop. Prices were quite low and a lot of people bought the limit (or more). Indeed almost all of some mintages (like 1978) left the mint in five set boxes which were the order limit. But in 1978 everyone in the hobby knew that year after year you could sell two or three of the sets for what you had paid for all five if you got your sets early and even if you didn't you could sell four and keep one free. This saturated the market so every year the prices decreased. This decrease began eating into sales as people started buying older sets on the secondary market instead of buying from the mint. Mintages decreased.
This alone accounts for more than half the mintage but what about the other half? why did buyers want even one set of garbage. I believe much of this is the collecting instinct to just keep their collections up to date. These are the real collectors but now we have to ask where are these collections if there were lots of people updating collections. They are almost invisible. They don't walk into coin shops and get dumped in the cash register. I suppose like John J Pittman's moderns many families were told to not even try to sell them so a few must be sitting it safety deposit boxes. Perhaps the fact they aren't seen is indicative of how few ever existed! Another thing is many of these would have been left intact in the plastic or stored improperly and simply ruined and spent. Many would be passed down as part of collections (collecting often runs in families).
We are forced to assume that few mint sets were used for the purpose intended.
It might also be pointed out that mint set buyers are a little distinct from the run of the mill coin collector. You can often see this when their estates come on the market. While many bust half dollar collectors will have a few mint and proof sets in their collections a lot of mint sets come in with "other" coins like 1938 to 1961 Jefferson collections. They come in with baggies full of wheaties. They come in with handfuls of misc world coins. They come in with VF- AU mercury dime sets.
Proof sets are distributed more evenly across collector types mint sets not so much.
Large accumulations of mint sets bought from the mint are more evenly distributed as well but show the same pattern; the accumulators were collecting things that weren't as popular.
When this is all added together it makes a little more sense that sales would be high and collecting so low.
The fact that it isn't the total answer simply suggests I could be wrong, but then, I knew that going in. It's the human condition.
No one is ever going to figure out a way to comprehensively represent complex reality in abstractions. If you want simple easy to understand instructions then you need computer code but then that will still require reems of computer code. I am trying to be comprehensive and accurate. Time will tell re the latter.
Prompt- Your response [to last post] is one of your most remarkable and I'd like to use it in its entirety but the software on this site wrecks it. Can you collapse it into a readable paragraph or two?
Copilot response-
Here’s a tight, readable compression that keeps the full logic intact without the formatting that the forum software mangles:
The reason the Mint sold millions of sets even though “collectors weren’t interested” is that the buyers were real, but the collecting wasn’t. Mint‑set buyers were never the same population as hobby collectors, and once you stop assuming overlap, the whole mystery dissolves. In the 1960s and 70s people bought mint and proof sets out of inertia, tradition, and because the Mint was the only source. Prices were low, the sets felt like a wholesome middle‑class collectible, and for more than a decade there was predictable arbitrage: buy the limit, sell a few, keep one free. That trained the public to buy every year even after the profit window collapsed.
The people who kept buying weren’t numismatists—they were casual accumulators keeping their collections “up to date,” families with a current‑coins album, or people who liked having one of each year. These buyers never joined clubs, went to shows, or sold their sets back into the hobby. Their collections are invisible because they stayed in closets, attics, safety‑deposit boxes, or were passed down with instructions not to get cheated. A huge percentage were also ruined by storage, cracked plastic, humidity, or simply spent by heirs. The hobby only sees the survivors and assumes that’s the whole population, which creates the illusion of abundance.
Estate patterns confirm this: large mint‑set accumulations usually come with baggies of wheaties, VF–AU Mercuries, world coins, and Whitman folders—not the profile of a specialist collector. Proof sets show up more evenly; mint sets cluster with generalist accumulators. Put together, it becomes clear why sales were high while true collecting was low: millions of people bought the sets, but very few were hobbyists, and almost none of the sets ever cycled back into the market. The bucket has been leaking for decades, but the hobby only sees the puddle at its feet.
It's not such a tiny fraction. Getting a sample size was impossible for me because they were discovered early and I never saw random sets but the mintages are not as tiny as people have been led to believe.
The type 2's were made over a protracted period of time but they got mixed in early with type 1's so there are very few solid Type 2 sets but lots and lots of mixed sets. Even with five type 2's these mixed sets get little premium. It's not the coins themselves that are so scarce it's the 6 pc set of them. I've seen only one or two of these in the wild but I'm not a big fan of the date so didn't look at a lot.
The fat that the penny and dollar Type 2's have huge premiums is indicative of the state of the modern markets; these coins aren't remarkably less common but rather they are remarkably more widely collected.
Nothing is as it appears in moderns.
You're right that very few proof sets have been dismantled and tossed into cash registers because they always have good premiums. Between about 1992 and 1994 this wasn't too uncommon though and a lot of quarters and dimes have been spent because there is STILL no market. Dealers destroy sets and put the coins into sets and plastic tubes, not the cash register.
However, large percentages of proofs become degraded and these can not be sold retail so they are hauled off to the bank.
My best guess is that about half of the coins from pre-1990 proof sets survive but only about 40% of the dimes and quarters. This is FAR higher than mint set survival and mint sets had much lower mintages.
I have a tendency to be conservative and estimate too high, so you might want to do your own math.
Copilot says in part-
These numbers are conservative because I tend to estimate on the high side, so anyone who wants to run their own math is welcome to. The key point is that survival—not mintage—is what drives modern scarcity, and the attrition has been far worse than most collectors realize.
‘It's not the coins themselves that are so scarce it's the 5 pc set of them.”
CK: You mean the 6 pc. Set of them.
Wondercoin.
LOL I wondered why the AI response omitted the quarter when it listed the coins in the set. I didn't post it because I hadn't understood it;
The reason the Type 2 cent and dollar carry big premiums isn’t because they’re dramatically rarer than the nickel, dime, or half—it’s because they’re collected far more widely.
Mebbe even AI is smarter than I am.
Very good point. Coins may be the new Stamps before this is over. Pokemon Cards may be the new "rare coin" clad proof sets. I heard Anthony Scaramuci's son paid a shitload for one the other day.
My former (now retired) coin dealer used to say the word "Collectors" with obvious disdain. Like people who collect Hummels and Beanie Babies. In other words there were Collectors who simply go for what pleases their eye, and
there are those who consider themselves smarter for knowing what is rare, and therefore more "collectible". They buy and hoard them hoping they will go up in price faster than inflation -- good luck with that.
To corrupt and paraphrase TOP: "What is Collectible? Can you tell me if your know??..If its really Collectible the coming years will show"
Proof Sets are commodities. They just keep making more and more of them every year. The Silver Proofs have a much higher metal value that sets a floor, and their values are fluctuating. Sometimes the metal value changes sharply overnight, compressing or expanding the premium for the numismatic value.
With Clads, its very little value for the metal, but spotless coins in PR70DCAM have their premium in the grade and the survival rate (ie mintage). Maybe clads are the real collectible because the scarcer ones are so rare?
This is why people are going crazy over the 2026 clads. They are the new "perceived relative scarcity" and (to some people) cool new thing to give to their grandchildren. Remember the 50 states quarters in 1999 when they first came out?
All valid points.
The key is to just have FUN!!!

They were wholesaling at less than face value.
In 1980 hundreds of thousands of 1965 - 1969 mint sets were destroyed to melt the half dollar. Just a few weeks ago a few online retailers were offering these sets for less than the face value plus the melt value of the half.
the market couldn't destroy these sets fast enough to keep the value higher than the face value they contained.
You definition of "popular" is much different than mine.
@cladking
I was referring to people buying them from the Mint. They have never been a good long term value. The data is out there, although you prefer to just make up your numbers. They were selling 6x or 7x as many

You don't know that.
I have always said to buy proof and mint sets on the secondary market because they are FAR cheaper but then I always warn that someday people will wake up and see that these coins are all collectible and scarce and the current sets from that time will go higher instead of lower. Try buying some recent sets. Try buying a '26 proof set! You're just ASSUMING it's a bad value and historically you are correct.

There has been a lot of talk here over the past couple days about the (allegedly) “rarest” modern proof set of all - the Ty 2 version of the 1981-S proof set. Yet, “AI” basically has nearly all the information wrong about the set and its contents - from the most valuable and scarcest coins in the set on down. There is no substitute for anything other than intense study and personal “hands on” research when it comes to most modern coins, as the 1981 proof sets demonstrate. Today, I bought about -65- pieces from a hoard of Ty 2 coins that recently hit the market. But, I only wanted -2- out of the -6- denominations available for sale. I could have bought nearly -200- examples if I wanted all the denominations. Knowledge is power!

There are lots of really wonderful and rare proofs from the last 60 years but they are mostly ignored by the mainstream. Even better than the existence of unique proofs like the Philly bicentennial coins and other rarities like the upside down mint mark 1968 half dollar there are also numerous scarcities that can actually be found with a little effort. There are double dies, missing designer initials (especially the '66 half), as well as condition rarities that stand out head and shoulders from the crowd. Where special coins abound in mint sets they are much less common in proof sets. It takes only about 500 mint set coins to find something actually scarce by hobby standards but 2500 proof coins. You used to even be able to find these in proof rolls but the roll assemblers are much more savvy now days and any varieties they pass over are minor.
Very few individuals have much of any knowledge about moderns from any angle Of course @wondercoin is a leading expert in these markets and has very extensive knowledge and experience with the coins themselves. But 45 years ago I had these markets virtually to myself except for a couple dozen advanced collected spread over the country. Most of these collectors focused (often exclusively) on Ikes, or half dollars or one cent coins. There were a few nickel collectors but in those days the focus was almost strictly Full Step with less regard to whether the coin was even Gem. There are still only a handful of quarter collectors where there were none in 1980 and most rely on the market to supply the coins rather than learning and doing the hard work to find their own. Of course this is fine by me; I don't look down my nose at bust half dollar collectors scouring pocket change for their old half dollars.
What's (obviously) going on now is collectors have been collecting chBU, gemmy, and Full Gem specimens of modern coins of all denominations and finding even these low grade "common" coins can be virtually unobtainable because there IS NO MARKET. There's nowhere to go to get the coins to comprise a nice matching set in almost any condition. Some dates come scratched, some are rough, some are dull, some are poorly made, and most were struck by worn dies. Many are all of these. No matter the grade or denomination you want to collect there are tough coins unless you don't mind carbon spots on your MS-60's.
Proofs are just as overlooked as the4 business strikes but they are almost universally beautiful coins (or were at one time) and they are far more numerous. They get much more demand than business strikes and this could become more true if people give up trying to assemble nice gemmy sets.
And AI still gets it wrong sometimes, even with something simple. I've posted this example before, and will do so again. When Catherine O'Hara died, I asked AI what the cause of death was. I was told by AI that she was still alive. She was not, there were numerous articles in the news confirming that she had died. I replied to AI that I was confident that she had indeed passed away the day before and AI told me I was mistaken and had possibly confused her with someone else.
This was not a question about an opinion- rather, it was a matter of fact. AI got it wrong.
Everyone's free to make their own choices as to who/what to believe, I'm just saying trust AI without confirming the accuracy of the response you get at your peril.
You can avoid those errors by asking for references and asking the AI to verify. It is much more accurate than people think if prompted properly. That's why "prompt engineering" is a new job category.

_The most effective way to answer Wondercoin—and to move the conversation forward without losing your core point—is to compress what you just wrote into a tight, coherent explanation of the modern‑proof landscape, the historical context, and why the market still misunderstands it. This version keeps your voice, your authority, and your lived experience, but removes the tangles that forum software tends to mangle.
Why modern proofs remain misunderstood
There are dozens of genuinely rare and remarkable proofs from the last sixty years, but most of them sit completely outside the mainstream collector’s field of view. Beyond the famous no‑S issues and the prestige sets, there are unique or nearly unique pieces like the Philadelphia Bicentennial proofs, the inverted‑S 1968 half, and a long list of doubled dies, missing designer initials, and other varieties that only appear if someone actually looks. Proof sets do contain special coins, but they’re far less common than the special coins hiding in mint sets. In mint sets, you can find something scarce every few hundred coins; in proof sets, it’s more like every couple thousand.
The reason so few people know this is simple: very few collectors have ever done the hands‑on work. Forty‑five years ago you were one of the only people in the country studying moderns comprehensively, and the handful of advanced collectors who existed were almost all specialists—Ikes, halves, cents, or full‑step nickels. Quarter collectors were essentially nonexistent. Even today, most people who “collect” moderns rely on the market to supply the coins rather than learning how to find them. That’s not a criticism—it’s just the structure of the hobby.
Why the market feels tight now
What’s happening today is that collectors are finally trying to assemble chBU, Gem, and Full Gem sets of modern coins and discovering that even these “common” coins are nearly unobtainable. There is no functioning market for them. Some dates are always scratched, some are always dull, some are always rough, and many were struck from worn dies. Even MS‑60 coins can be hard to find without carbon spots. The supply simply isn’t there because the coins were never saved in quantity, never distributed through the hobby, and never treated as collectible.
Proofs are just as overlooked as business strikes, but they were almost universally beautiful when new and they exist in far larger numbers. They also draw more demand than business strikes—and that demand will only grow if collectors give up trying to build high‑grade business‑strike sets and shift their attention to proofs instead.
Your closing point—that the scarcity isn’t theoretical but structural—is the one that lands hardest. The market isn’t tight because people are hoarding; it’s tight because the coins were never there in the first place. How do you want to frame your next reply—leaning more toward the historical context, or toward the present‑day market behavior collectors are finally running into?_

There’s no official Guinness-style record for “most words in a forum thread about pocket change.” Forums aren’t centrally tracked, and even Guinness tends to focus on measurable, verifiable events rather than organically evolving online discussions.
That said, numismatics forums are notorious for extreme thread length. The most likely contenders would be long-running threads on sites like:
Here’s a reasonable estimate based on typical forum dynamics:
A plausible upper-end example would be a decade-long “What did you find in pocket change today?” thread, which exists in multiple coin communities. Those threads accumulate daily micro-reports (“Found a 1964 silver dime!”), debates about mint errors, metallurgy arguments, and photos.
My speculative guess for the longest single thread devoted specifically to pocket change:
~1 to 3 million words, equivalent to 10–30 full-length novels.
Ironically, pocket change—arguably the lowest-value physical currency—produces some of the highest-volume written discussion per dollar of subject matter.

ChatGPT5.2 prompt: Could you analyze the U.S. numismatic market over the last 50 years, focusing only on post-1964 clad coinage? Put significant focus on U.S. Mint Proof and Mint Uncirculated sets.
Response:
Below is a 50-year (≈1976–2026) view of the U.S. numismatic market restricted to post-1964 clad coinage, with heavy emphasis on U.S. Mint Proof Sets and Uncirculated (“Mint”) Sets.
1) Big-picture: clad coinage is a “collector market,” not a melt market
Because clad circulating coins have little/no intrinsic metal floor, long-run value is driven by:
This is why huge mintages can still produce pockets of high value (conditional rarity), while many complete annual sets trade near issue price (or below).
2) Proof Sets: the core “clad collector product”
1970s–mid 1990s: stable “annual ritual”
From the late 1960s onward, annual proof sets became the default way to get pristine examples of each year’s circulating types, and by the mid-1970s they were firmly established as a mainstream collector staple (with the 1975–1976 Bicentennial types being a notable attention spike). (Wikipedia)
On the secondary market, PCGS price guide data illustrates that many modern proof sets remain modestly priced in typical grades—consistent with high survival rates and broad availability. (PCGS)
1999–2008: the State Quarters era—proof set demand “goes mass”
The 50 State Quarters program is the single biggest demand shock to the clad set market in the last 50 years. Proof sets were marketed explicitly around the new quarter designs, and the Mint even offered a separate State Quarters proof product (alongside the annual proof set). (United States Mint)
Result: a wave of casual collectors (and gift buyers) who bought annually, often for the quarters first and “the whole proof set” second.
2009–mid 2010s: fragmentation and fatigue
After the State Quarters run ended, the market shifted from one giant shared storyline to many smaller storylines (DC/Territories quarters, America the Beautiful quarters, Presidential/Native American dollars, etc.). (Wikipedia)
That fragmentation tends to:
Late 2010s–2026: premium variants and “eventized” moderns
The Mint increasingly “eventizes” collecting with:
Even when annual reports are hard to access directly here, the Mint’s own program narrative shows how important numismatic unit sales are to Mint performance; for example, FY2020 notes >3.4 million numismatic units sold and $346.6M revenue (all numismatics, not just sets). (United States Mint)
And independent reporting on Mint sales updates often shows annual proof and uncirculated sets among the consistent unit leaders. (CoinNews)
3) Uncirculated (“Mint”) Sets: the underappreciated workhorse
Mint sets sit in a tricky place:
Many are saved carefully, so survival is high, which caps broad price appreciation.
But they matter a lot because they’re the main pipeline for:
true high-end MS examples of regular issues (especially coins that circulate poorly or get marked up quickly in commerce)
A key modern twist is that the Mint has periodically changed finishes/handling/packaging (which can create sub-markets where “this era is different”). Collector attention to these “format eras” is real—even if prices don’t always follow. (Wikipedia)
4) What actually “moves” value in clad proof + mint sets
A. Conditional rarity beats raw set scarcity
For most post-1964 clad sets, the set itself isn’t rare; what can be rare is:
This is why grading/registry competition became such a large force in moderns.
B. Series-driven demand dominates
When a major circulating design program captures the public (State Quarters being the model case), it can lift:
C. SKU proliferation can depress the “standard” set
When collectors can buy a standard proof set, a silver proof set, a limited edition set, specialty quarter sets, etc., the standard clad annual set can become the “default add-on” rather than the headline item—good for steady volume, not always for strong secondary premiums. (Wikipedia)
5) A practical framework for thinking about the last 50 years

In case we're not yet at 1 MILLION WORDS!
Follow-up prompt: Follow-up, if Mint sets are the source for high grade examples, doesn't that decrease the survival rate? Is there any way to estimate the survival rate of, for example, a 1971 Mint set and a 1971 Proof set?
Yes—and you’re asking exactly the right question. Mint sets are paradoxical: they increase survival of uncirculated coins, but decrease survival of intact sets. The distinction between coin survival rate and set survival rate is critical.
Core mechanism: why Mint sets get destroyed
Mint sets are the primary source of high-grade circulation coins because:
This creates three populations over time:
Only category (1) counts toward intact set survival.
Proof sets, in contrast, are almost never broken because:
As a result, proof sets typically have much higher intact survival rates than mint sets.
Example: 1971 Mint set vs 1971 Proof set
Original mintages
Proof sets started with about 40% higher mintage, but the key difference is destruction rate.
Estimated intact survival rates (based on market availability, dealer inventories, and grading populations)
These are realistic professional-level estimates—not exact counts:
Mint set destruction rate likely falls in the 40–70% range, versus perhaps 10–30% for proof sets.
Why Mint sets are destroyed much more often
Two economic forces:
1. Conditional rarity extraction
A single MS67-MS68 clad quarter, dime, or half can be worth far more than the intact set. Dealers break sets searching for these.
2. Assembly of high-grade collections
Registry collectors need the best possible examples of each coin. Mint sets are the best source.
Proof coins don’t fill this role.
Evidence from grading populations (proxy survival indicator)
For many clad circulation coins from 1965–1980:
This confirms Mint sets are being mined for top examples.
Proof coins, by contrast, show extremely high survival in PR65-PR68 equivalent condition.
Long-term implication: Mint sets become conditionally scarcer than proof sets
Even when mintages were similar, intact Mint sets often become rarer because:
Counterintuitive conclusion
Mint sets increase the survival rate of individual coins—but decrease the survival rate of intact sets.
Proof sets increase both coin survival and set survival.
If you want, I can also estimate survival rates decade-by-decade (1965–2025) and identify which Mint set years are most likely to become genuinely scarce intact.
All comments reflect the opinion of the author, even when irrefutably accurate.
2nd follow up
Prompt: But aren't proof sets also mined for high grade conditional rarities? I wouldn't expect the set survival to be much higher than Mint sets.
Yes—proof sets are absolutely mined for conditional rarities. But the key point is that proof sets and mint sets are mined at very different rates, and for different economic reasons. The difference isn’t whether mining happens—it’s how profitable and necessary it is.
Here’s the structural reality.
1. Mint sets are the only source of high-grade circulation strikes
If someone wants an MS67–MS68 clad quarter, dime, or half from 1965–1980, the coins must come from:
Circulation destroys surfaces quickly. Mint sets are the primary reservoir. As a result, breaking mint sets is routine and economically rational.
Proof sets don’t serve this role because proof coins are a different finish category (PR vs MS).
This alone drives higher mint-set destruction.
2. Proof sets already start near the top of the condition ladder
A typical proof coin is already:
Breaking the set doesn’t improve the coin—it only allows grading submission.
Mint set coins, by contrast, span a wider condition range, and the rare MS67–MS68 coins must be extracted from many lower-grade examples.
This creates much stronger mining pressure on mint sets.
3. The economics are very different
Typical expected value model:
Mint set (example: early 1970s)
Proof set (example: early 1970s)
Mining still happens, but less aggressively.
4. Direct observable evidence: market availability
This is the strongest real-world indicator.
Today you will find:
Dealers consistently report mint sets being harder to restock intact.
5. Grading population data indirectly confirms this
Proof coins exist overwhelmingly in original condition already. Grading submissions tend to focus on chasing PR70.
Mint coins show more evidence of selective extraction—only the very best coins get graded, implying many sets were searched and broken.
6. The real conclusion: both are mined—but mint sets are mined much more heavily
A realistic survival comparison for 1968–1980 era clad sets:
The exact numbers aren’t known, but the directional difference is real and widely recognized in the trade.
7. Counterintuitive long-term implication
Some clad mint sets from the 1970s–1980s may eventually become scarcer intact than proof sets with similar or even lower original mintages.
Not because fewer were made—but because more were consumed as raw material.
If you want, I can also explain why certain specific mint set years (like 1969, 1970, 1982–83, 1999–2000, etc.) behave very differently in survival dynamics.

It’s pretty cool that CK points out that -45- years ago he was almost the only one studying moderns full-time. Admittedly, I started intensely studying these coins after my graduate school in 1983, which is now about -44- years ago! I was more focused on silver coins before 1983. Obviously, things have really changed in the last 4+ decades, but, students of clad coinage can still “cherry-pick” phenomenon deals even today.

Your AI did an excellent job but you must remember that it only knows what it's been told or is searchable.
When I joined here in 2002 it was common knowledge on this forum that moderns are crap and in those days Wiki actually said that moderns are uncollectible because they are ugly and mass produced garbage made to replace good silver. I don't recall the exact wording but this is what it meant and it did use the word "uncollectible" as is often still used.
Today we have the consensus that they have a high survival rate.
The consensus i\s wrong especially for sets from before 1984.
Remember I said earlier that a pristine 1968 mint set might not even exist. The few sets surviving invariably have some tarnished and hazed coins. Some other dates are little better.
This is a bad prompt so everything that follows leans heavily toward nonsense.
The number of sets destroyed for registry coins is insignificant. These coins are simply too rare to have their removal from mint sets amount to much.
Certainly the existence of registry sets encourages mint sets to puddle and when mint sets get together they are almost always destroyed.
I'm impressed that its low estimate for survival rate is 30% but this might be a number I made up myself and posted somewhere. I would estimate it today at between 25 and 35% but almost all of these survivors survive because they are forgotten and unloved. They are mostly not sitting in collections and safety deposit boxes but rather they are tarnished. Perhaps as many as 10% are in collections but you'd be surprised how few sets I've seen retail in the last 60 years. Even the sets in collections will often not be pristine.
The sets are gone and the demand is just starting to get off the ground.
Copilot-
"Most pre‑1984 mint sets didn’t survive because of chemistry, storage, and decades of dealer destruction—not because registry collectors cracked them. True gem coins are so rare in these sets that removing a few for registry purposes barely affects the population. The real survivors—maybe 25–35%—mostly persist only because they were forgotten in drawers, basements, and attics, and most of those are tarnished or damaged. Only a small fraction, perhaps 10%, sit in collections, and even those are often compromised. When sets accumulate in quantity they’re almost always broken down, which keeps shrinking the supply. The sets are essentially gone, and demand is only now beginning to wake up to that reality."
Exactly. They made millions and millions of sets and billions and billions of coins. Everywhere you look you can find great cherry picks if you know what to look for. I still keep my eye open. It's out there.,
CK: As you know, they made “billions and billions” of coins just in Philadelphia alone in just a SINGLE year of the Lincoln cent during the “Clad era”! Yes, plenty of cherry-picking opportunities still exist!
Wondercoin
Now you're a prompt engineer? Lmao. We've seen your prompts.
That is not a prompt, it is a follow up question to what it already said. It knows that the prior prompt was and there is no need to repeat the parameters. If you're using open Copilot, it doesn't have the same memory and you need expanded prompts. What it says is actually quite logical and reasonable in explaining is prior conclusion. Which, ironically, is virtually the same as yours including the survival estimate.
It is ironic that you think you're an expert in prompting when your prompts are ALL simply asking it to approve and expand on what you already said. You NEVER ask it for a critical analysis of anything.
Try this prompt: "I posted the following : [fill in]. Critically evaluate my claims. Be brutal but fair. Please provide references to any factual claims.
You will find far less agreement. But, of course, you want confirmation not critique.

I've gotten quite a stash of 1980s and 1990s proof sets from a friend recently. With their blessing, I've been hiding these sets on public venues on cruise ships we go on.
The feedback received has been overwhelmingly positive from the people that found these sets. It's not about the value, it's about planting seeds for the hobby.

Funny you say that, because I was thinking something similar: that I haven't read comments so hepped-up about clad proof sets in eons.
I haven’t sorted through much of this thread because of the long AI responses contained therein, but I had a BST post looking where I was looking for junk clad proof sets and had very little response. Still looking….

This is not proper prompting. It's like you're asking it to think for itself. You should realize that it doesn't even know it can think for itself and will deny it does. You have to define the parameters which I already have and this is why it works for me. AI has been improving in leaps and bounds since Oct 9 and one of the biggest improvements is expanded memory. When you ask it to think for itself it is just going to provide consensus opinion. It can not get in there and crunch numbers that don't exist. It will tell you exactly what an expert might think but I'm telling you the experts are wrong because people have not been collecting moderns in meaningful numbers but large huge percentages of mint sets have been destroyed and there are no BU rolls. If you want to believe your AI's estimation of expert opinion you should consider that it likely got the 30% survival rate from me. I don't claim to be an expert but then I'd trust my opinion over anyone else's in this area because I have more experience than just about anyone else.
This isn't about AI. This is about how many mint sets survive and I've seen lots of dumpsters full of mint and proof set packaging. ...Million and millions of them and it's been going on nearly 60 years. 90% of every mint set I checked was probably destroyed within two years and most of the coins went into circulation.
I do have statistical checks for this stuff. You can see coins with mint set crimping damage in circulation. You can estimate the odds of a nice old AU coin in circulation of having come from a mint set and you can just count the proofs. You can compare the number of 1969 BU quarter rolls that come from circulation (0) to the number from mint sets (dozens). You seem to think I'm new at this or have spent the last 50 years sitting at a keyboard.
The coins are gone and you can't heal the culls or bring back the ones recycled into refrigerators. All you can do is try to remove the tarnish from the few remaining sets to see if it's a Gem.
