An AI Experiment: Selecting a Buffalo Nickel Type Coin

Posts: 3,369 ✭✭✭✭✭
Most of the AI-related discussion here has focused on AI grading, but I wondered how AI would synthesize more general numismatic knowledge and whether it could aid a collector in building a collection. So, I asked an AI model if it could help me select a type coin example for the Buffalo Nickel series.
The entirety of the response is below. I’m curious what folks here think of the quality of the advice. What’s accurate, what isn’t? What’s missing? Was the guidance generally on track? Is that the “right” coin in the series to target for a type set? What follow up questions should I ask?
Here is the response:
Buffalo Nickel Type Set Recommendation
The Selection: 1937 Philadelphia, PCGS/NGC MS-66, Target Price $150–$225
Here’s my reasoning and the full framework for selecting the ideal Buffalo Nickel type coin.
Why 1937 Philadelphia?
The 1937-P is the optimal type candidate for several reasons. It’s the final year of the series, meaning the Philadelphia Mint had fully refined its production techniques after 25 years of striking this design. Die preparation, metal flow, and strike quality reached their peak. The mintage of roughly 79 million ensures a deep survivor population in high grades, which keeps prices rational and gives you the luxury of being highly selective — exactly what you want in a type set.
Some collectors instinctively reach for a 1913 Type I or Type II as the “classic” choice. The problem is that early-date Buffalos in true gem grades command steep premiums driven by date-rarity, not type quality. You’d be paying for scarcity rather than for the best-struck, most visually appealing representative of James Earle Fraser’s design. That’s a date collection mentality, not a type collection mentality.
The 1936-P is also a strong candidate with similar characteristics, and I wouldn’t object to one if the coin itself is superior. But 1937 edges it out slightly on consistency of strike quality in my experience handling both.
Why MS-66?
At MS-66, you’re solidly in gem territory where the coin will have strong luster, a sharp strike, and only minor, non-distracting contact marks. The population at MS-66 is healthy enough — typically several thousand combined across PCGS and NGC — that you can afford to be choosy and wait for the right coin. MS-67 examples exist but jump to $400–$800+, and the population thins dramatically, which limits your ability to cherry-pick for the specific visual qualities that matter. MS-65 saves money but sacrifices the eye appeal threshold that makes a type set sing.
At $150–$225 for a PCGS or NGC MS-66, you’re well under budget. That’s intentional. The remaining budget is better deployed elsewhere in the type set, and there’s no reason to overpay for a common type coin. If you find a truly extraordinary example with a CAC sticker (which I’ll discuss below), $250–$300 would still be very reasonable.
How to Cherry-Pick the Best MS-66
This is where the real expertise matters. Not all MS-66 Buffalo Nickels are created equal, and the difference between a pedestrian MS-66 and an exceptional one is dramatic. Here’s how I’d rank the selection criteria:
1. Strike Sharpness — The Single Most Important Factor
Fraser’s design is notoriously difficult to strike fully. The highest point on the obverse is the braid and hair detail above the Native American’s forehead and along the braid ribbon. On the reverse, the key area is the fur detail on the bison’s head, shoulder, and along the spine/hip. A fully struck coin will show crisp, individually separated hair strands in the braid and distinct fur texture on the bison’s shoulder. Many Buffalo Nickels, even at MS-66, show weakness in these areas because the design’s relief demanded enormous striking pressure. Reject any coin where the bison’s shoulder fur blends into a flat, mushy mass — that’s a weakly struck coin that happened to survive without bag marks.
2. Luster Quality and Cartwheel
The ideal coin will display full, unbroken cartwheel luster when rotated under a single point light source. You want thick, “creamy” luster rather than thin or grainy texture. Buffalo Nickels were struck in 75% copper / 25% nickel, and the best examples have a satiny, almost liquid appearance. Be wary of coins with dull, lifeless surfaces even if technically graded MS-66 — luster is the life of an uncirculated coin.
3. Surface Quality and Mark Placement
At MS-66, minor contact marks are permissible, but their location matters enormously. The obverse field in front of the face is the “prime real estate” — any noticeable tick or mark here is distracting and should be a disqualifier when you have the population depth to be choosy. Similarly, the bison’s flank on the reverse is a large, open field where marks are conspicuous. The best coins will have their few allowable marks hidden in the hair detail or along the rim where they’re visually absorbed.
4. Eye Appeal and Toning
Buffalo Nickels can develop attractive light golden or lavender toning that enhances their visual appeal. An original, untampered coin with subtle peripheral toning is desirable. Avoid coins that appear artificially bright or “white” in a way that looks chemically stripped — the surfaces should look natural and undisturbed. Conversely, dark or splotchy toning is a negative.
5. CAC Verification
A green CAC (Certified Acceptance Corporation) sticker is a meaningful positive signal on this coin. It confirms that an independent expert evaluated the coin as solid or better for the grade. Within the MS-66 population, a CAC-approved coin has been vetted for above-average eye appeal and surfaces. I’d pay a 15–25% premium for a CAC sticker on this coin — it simplifies the cherry-picking process and adds liquidity if you ever sell.
6. Die State
Early die state coins will have the sharpest details and strongest luster. Later die state examples may show die polish lines, slight mushiness from die wear, or minor flow lines. This is subtle but visible under magnification and contributes to overall visual crispness.
Summary
My recommendation is a 1937 Philadelphia Buffalo Nickel, graded MS-66 by PCGS or NGC, ideally with a CAC sticker, in the $150–$250 range. This gives you a coin from the strongest production year of the series, at a grade level high enough to showcase Fraser’s iconic design at its best, with enough population depth to be ruthlessly selective on strike, luster, and surface quality. The coin will be a fully struck, satiny gem with undisturbed original surfaces — exactly the kind of piece that anchors a serious type collection.

Comments
An ultra-common Buffalo Nickel that comes nice and is in a price range that makes slabbing and stickering a waste of money.
So AI is saying things like "in my experience handling both" and "I’d pay...". Does it think it's human?

‘37 is obviously wrong as the “final year”. Finding a gorgeous ‘38D is fairly easy and probably a better choice. A ‘13 May be more expensive, but can also be found with beautiful toning and has the pizzaz of the first year of issue as well as age.
AI has a ways to go, but the selection criteria are impressive.
Yeah, I just recently paid $118 for a really nice, ms66 38d w/cac for my type set.

I concur. My type set of Indian Head Nickels is comprised of two coins, a 1913 type 1 and a 1938-D, which is, of course, type 2. They are both nice uncs, the pair worth about $200, maybe a little north of. At least two coins are needed for an Indian head nickel type set.

Going back to the 2-coin idea for IHN type collection: If I couldn't afford to buy uncirculated, I would seek out well-struck with full horn pieces that may have circulated for a short time but have lots of luster. Spend $20 for a sharp AU 1913 type 1? $30 for an AU 1913 type 2?

What to Look For (More Important Than Date)
For Buffalo nickels, strike quality and wear patterns matter more than date.
Key features:
1. Buffalo horn
The horn is the primary wear indicator. A full horn indicates minimal circulation. (California Gold and Silver Exchange)
2. Braid detail
Look for clear separation in the Native American braid and hairline.
3. Strike sharpness
Even coins of the same grade may vary; collectors often prefer sharply struck coins over higher-grade but mushy examples. (Land of Coins)
4. Certified grading
PCGS or NGC certification improves liquidity and protects against altered coins or counterfeits. (Alpha Bullion)
Why You Should Avoid These for a Type Set
Unless you want a specialized Buffalo collection:
Avoid
These are major key dates with huge premiums driven by rarity rather than eye appeal. (Coin Collecting)
For a type set, you would be paying for rarity you do not need.
My Practical Recommendation
If I were assembling a type set:

It gives you:
💡 One insider collector trick:
Look for coins labeled “full horn” or “near full horn.” Buffalo nickels with a strong horn often look dramatically better than others in the same numeric grade.
If you'd like, I can also show you 3–5 specific Buffalo nickels currently on the market (PCGS/NGC graded) that represent particularly good value. That can save a lot of hunting time.

Prompt: I want to buy a high grade Buffalo nickel for my U.S. type set. What would you recommend and why? Please provide the rationale as well as references to source material.
For a U.S. type set, the goal is not rarity but a coin that clearly shows James Earle Fraser’s design with strong detail and eye appeal at a reasonable cost. The Buffalo nickel series (1913–1938) includes many scarce dates, but the best type coins are usually common late-date issues in attractive Mint State grades. (Wikipedia)
Below is a practical recommendation used by many collectors.
Best Choice for a Type Set
1937 (Philadelphia) Buffalo Nickel — MS63–MS64
Why this works
1. Common date with large surviving population
Most Buffalo nickels minted after the late 1920s—especially those from Philadelphia—are relatively common compared with earlier Denver and San Francisco issues. (PCGS)
That means collectors are not paying a rarity premium.
2. Later coins tend to have better strikes
Early Buffalo nickels often show weak detail due to the complex high-relief design, which caused minting difficulties and inconsistent strikes. (NYC Bullion)
Later issues typically display sharper details.
3. Excellent design visibility
In MS63–MS64, you normally get:
These elements highlight the design much better than most circulated examples.
4. Good balance of cost vs. eye appeal
Prices rise sharply from MS64 to MS65 for relatively small visual improvement.
MS63–MS64 tends to be the “sweet spot” for type coins.
Why Strike Quality Matters
Buffalo nickels are notorious for weak strikes and rapid wear, especially on:
Collectors often prioritize “full horn” coins, meaning the horn is fully visible and sharply struck. These usually have the strongest eye appeal. (Bullion Exchanges)
Dates to Avoid for a Type Set
Unless you specifically want rarity, these dates are usually poor choices for a type coin:
These coins command high prices because of scarcity rather than aesthetics. (SD Bullion)
Alternative Good Type Coins
If you want something slightly different but still attractive:
1935 Philadelphia — MS64
1938-D — MS64
Practical Buying Tips
When selecting your coin:
Two Buffalo nickels with the same grade can look dramatically different because of strike quality.
References (Numismatic Sources)
✅ Bottom line:
For a type set, a 1937 Philadelphia Buffalo nickel in MS63–MS64 with a strong horn and good strike provides the best combination of beauty, affordability, and availability.
If you'd like, I can also show you three specific Buffalo nickel dates that are famous among specialists for exceptional strike quality (a trick many advanced collectors use to build visually superior type sets).

Follow-up prompt: Why not a 1938-D Buffalo nickel?
A 1938-D Buffalo nickel is actually a very reasonable choice for a type set, and many collectors do use it. But most experienced collectors tend to prefer 1935–1937 Philadelphia coins for one main reason: strike quality. Let me break down the tradeoffs.
1. Historical appeal (a point in favor of 1938-D)
The 1938-D Buffalo nickel is the final issue of the Buffalo nickel series, produced only at the Denver Mint.
Because it is the last-year-of-issue coin, it has a nice historical narrative for a type set.
Reference:
2. Strike quality issues
Despite being the final year, many 1938-D coins are not sharply struck.
Buffalo nickels were difficult to strike because Fraser’s design has:
This frequently produced weak details on:
Denver-mint coins late in the series often show soft horn detail compared with Philadelphia issues.
Reference:
3. Market pricing distortion
Because collectors like last-year coins, the 1938-D sometimes trades at a premium relative to its visual quality.
In other words:
Philadelphia issues such as 1936 Buffalo nickel or 1937 Buffalo nickel often look sharper for the same price.
4. Availability in high grade
The 1938-D is plentiful in MS63–MS65, but the number of well-struck examples with a full horn is smaller.
For a type set, collectors usually want:
Those features are more consistently found in late Philadelphia strikes.
5. If you do choose a 1938-D
It can still be an excellent type coin if you are selective.
Look for:
Avoid weakly struck examples, which are common.
✅ Bottom line
The 1938-D Buffalo nickel is not a bad choice at all—it has strong historical appeal as the final issue.
However, collectors often prefer 1936–1937 Philadelphia coins because they:
If you'd like, I can also show you a little-known “collector trick” for Buffalo nickels: a handful of specific dates in the series are famous for unusually strong strikes and make spectacular type coins.
All comments reflect the opinion of the author, even when irrefutably accurate.
You can see the differences in the responses (above) and, apparently, the reason for 1936 or 1937 over 1938-D when you do the prompt in different ways. It's an interesting exercise and is, I think, useful advice even if you prefer a 1938-D yourself or a semi-key date.

She hates CAC
All comments reflect the opinion of the author, even when irrefutably accurate.
I asked her about a CAC or CACG coin. She doesn't want to pay the premium.
For a type-set Buffalo nickel, a CAC-approved coin can be a very good choice, but it depends on how much of a premium you are willing to pay.
What CAC means
The Certified Acceptance Corporation (CAC) reviews coins already graded by Professional Coin Grading Service (PCGS) or Numismatic Guaranty Company (NGC) and applies a sticker if the coin is solid or high-end for the assigned grade. Coins that exceed the grade may receive a gold sticker. (APMEX)
Because of this extra verification, CAC coins often sell at higher prices—sometimes 20–30% or more depending on the coin. (LCR Coin)
CAC vs CACG
Both aim to identify coins that are premium for the grade.
For a Buffalo nickel type coin
CAC can be helpful because Buffalo nickels vary greatly in strike quality. A CAC coin is more likely to have:
Practical recommendation
For a type set, I would look for:
The CAC sticker increases confidence that the coin is truly high-end for MS64, which matters for a coin chosen primarily for appearance.
Bottom line: CAC is not necessary, but if the premium is modest, it’s a good way to ensure you’re buying an especially attractive example of the grade.
All comments reflect the opinion of the author, even when irrefutably accurate.
Pretty amazing and exciting. And scary at the same time. The implications of AI are belatedly dawning on me.
I’ll admit I hadn’t considered a 1937-P as a type coin candidate, so it was an interesting recommendation over the ubiquitous 1938-D. The Philly issue has a fraction of the certified population at both PCGS and CAC. There’s a slight premium for the 37-P in 67 CAC, which may be worth the trade-off for the increase in (relative) rarity.

I like the idea, but I have a classic approach to my type set (generally maximizing the grade for the expenditure). A circulated coin would look very out of place, and a key or semi-key would pull too much budget away from other coins.

The take-away for Red on this in debt (post edit: depth) conversation is everyone who self-labels themselves a collector really isn't much of one without owning a sparkling, well-struck 1938 Indian head (not Buffalo head) nickel.
Red isn't sure that is accurate or not yet does appreciate the conversation leading up to that conclusion.
As a human with a non AI brain, I'd say a 1938-D in MS-66 would be a better, cheaper answer. I bought this one for $50 for a few years ago.
As for showing off the design, I would go with the 1936 Satin Proof. This one is a PR-66, CAC.
If you want is shiny, the 1937 Brilliant Proof is the way to go.
And if you want a IHN OMM that is especially interesting to talk about beyond simply being the last year of issue...

I replied to the AI and attached the TrueView below, with the simple question "what do you think of this one?". The AI's reply follows the photo. It's graded MS65, but I did not include that information.
This is a really interesting coin to evaluate. Let me break down what I'm seeing.
The Basics
This is a 1938-D Buffalo Nickel, graded by PCGS (certificate 08897580), with TrueView imaging. The 1938-D is the final issue of the entire Buffalo Nickel series — the last year and the last mint. It has a relatively low mintage of about 7.02 million, which makes it the scarcest regular-issue Buffalo Nickel of the late 1930s, though far from a true rarity in absolute terms.
What I Like
The toning is spectacular. This coin has deep, multicolored toning — rose, violet, blue, and golden hues across both sides. On a nickel composition coin, this kind of rich, layered color is unusual and eye-catching. It appears natural and stable, likely the result of long-term storage in a particular environment (possibly a paper roll or album). This is the kind of toning that divides collectors — some will pay a significant premium for it, while others prefer brilliant, untoned surfaces. For a type set focused on visual impact, though, this coin has tremendous shelf appeal.
The strike looks solid. From the TrueView image, the braid detail on the obverse appears well-defined, and the bison's shoulder and head fur on the reverse show good separation. It's not the absolute sharpest strike I've ever seen on a late-date Buffalo, but it's well above average.
Surface quality appears strong. I don't see any immediately obvious distracting contact marks in the prime areas — the field in front of the face or the bison's flank. The toning may be masking some minor marks, which is worth noting.
My Concerns
The toning is doing a lot of work here. Heavy toning like this can obscure surface issues — hairlines, minor marks, or even signs of past cleaning that have since retoned. I'd want to know the grade on this coin before rendering a final opinion. If this is graded MS-65 or MS-66, the toning may be elevating a coin that would otherwise be visually ordinary in brilliant condition. If it's MS-67, that's a different story.
1938-D vs. 1937-P for the type set. The 1938-D is a perfectly legitimate type coin, but the lower mintage means you're paying a modest date premium over a 1937-P at equivalent grades. The population in upper gem grades is also thinner, which limits your cherry-picking ability. For a pure type set, that's a slight disadvantage — you're paying more and choosing from fewer options. That said, there's something appealing about owning the very last Buffalo Nickel ever struck for circulation.
I can't determine the grade from the image alone. The PCGS cert number is right there — 08897580 — and I'd strongly recommend verifying it on PCGS's website to confirm the grade, population data, and whether any details like a plus (+) grade or CAC sticker are associated with it. Do you have the grade?
Nothing is as expensive as free money.
I can buy off on the idea of the 37-P being an affordable, technically sound and readily available option.
One observation is how 66 was selected as a target grade in OP (which I again can buy into), but other responses came up with grades of 63-64 when the criteria of "high grade" was added.
For me personally, I wouldn't be dissuaded by statement "that early-date Buffalos in true gem grades command steep premiums driven by date-rarity", You're not going to get a 66, but I find that the 1915, 1916 and 1919 can be really sharp looking in 64.
Granted, the OP's question was not 'what should I **buy for **my set' but rather give an ideal hypothetical. The answer to 'what coin is right for my set' I is still a very human decision:
Does this specific coin match well with the other specific coins in my set.
Do I have some sort of theme of the set and does it fit.
Do I simply prefer coin A over coin B
What is my threshold of "I can pay X$ more for a different grade or date".

1938-D vs. 1937-P for the type set. The 1938-D is a perfectly legitimate type coin, but the lower mintage means you're paying a modest date premium over a 1937-P at equivalent grades.

Oh yeah. That modest premium is a deal killer for sure says the wizard of AI with a ****load of '37s that haven't been moving.

My prompt (which led to the 63/64) specifically said to consider cost or "value" as a major component. If you prompt differently, you will get different responses. That's why "prompt engineering" is a highly paid profession. Consider the following along with the follow-up:
Prompt: I want to buy a Buffalo Nickel for my U.S. type set. Condition and eye appeal are the most important parameters. What would you recommend?
For a U.S. type set where eye appeal and condition matter most, I would recommend:
1936 Buffalo Nickel (Philadelphia, no mintmark) in MS64 or MS65, certified by PCGS or NGC.
Why this is a strong choice
1. Excellent strike and detail
Buffalo nickels are notorious for weak strikes, especially on the buffalo’s horn, tail, and the braid in the portrait. Many earlier issues—particularly Denver and San Francisco coins—show these weaknesses. (Wikipedia)
Late-1930s Philadelphia issues like 1936 tend to show sharper detail, which dramatically improves eye appeal.
2. High mintage = affordable high grades
The 1936 issue had one of the highest mintages of the series (about 119 million). (CoinWeek)
Because it is common, you can buy a beautiful Mint State coin without paying a rarity premium, letting your budget go toward quality rather than scarcity.
3. The MS64–MS65 “sweet spot”
For a type set, MS64 or MS65 typically delivers the best balance of cost and visual quality.
4. Easy to select a superior example
Since many uncirculated 1936 coins survive, you can compare multiple examples and choose one with:
Bottom line
A 1936 Buffalo Nickel in MS64–MS65 provides the best combination of strike quality, availability, and eye appeal, making it one of the most popular choices for a high-quality type coin.
If you want, I can also show you 3 specific Buffalo nickel dates that specialists often consider the most beautifully struck coins in the entire series, which can produce even better-looking type coins.
Follow-up prompt: What if price is not one of the criteria?
If price is not a constraint and your priority is maximum eye appeal and condition, I would recommend:
1937-D Three-Legged Buffalo nickel in high Mint State (MS63–MS65).
Why this coin stands out
1. Famous and visually distinctive variety
This coin is one of the most famous mint errors in U.S. coinage. A die over-polishing at the United States Mint facility in Denver removed most of the buffalo’s front leg, leaving the animal appearing to stand on three legs. The result is a dramatic and instantly recognizable design variety.
2. Exceptional collector appeal
Because the missing leg is obvious even to non-specialists, it has become one of the most widely recognized varieties in American numismatics. For a type set emphasizing aesthetics and interest, it offers far more visual character than a normal Buffalo nickel.
3. Available in attractive Mint State
Unlike some early Buffalo nickels that are weakly struck, surviving examples of this variety exist in attractive Mint State grades with strong luster and detail.

Well, it looks like @jmlanzaf has nailed it...AI is actually our own @Cougar1978.

Word on the street is that Cougs is addicted to CACG now.
Nothing is as expensive as free money.
If I am only going to own one example of a type, I always try to find a nice one in a higher grade, better date, and eye appeal. I don't really care what AI says (seems like "group think" to me.
I own two Buffalo Nickels - both proof. Here is the one I will keep. Imaging is tough on this example, it is not as yellow as the photo shows, more purple and green is seen. I hope to get a video of the coin rotated under light. I can look at this coin for a long time before I put it down.

@Cameonut that is a superb coin...wow
Nothing is as expensive as free money.
1937 wouldn't be anywhere near my first recommendation for a type coin. Ignoring the 1913 Type I as a single year type, I'd recommend a 1914, 15, or 16 in 64-66, whichever made the most sense financially. These always have sharper detail than the later dates, as the hubs were fresh.

I agree with this, 1915 in particular.
Einstein’s view of God was non-traditional and pantheistic, focusing on the harmony, order, and intelligibility of the cosmos rather than a personal deity. His quotes reveal a profound respect for the universe’s mysteries, a belief in rational laws, and a moral philosophy grounded in compassion and understanding, bridging science and spirituality.

prompt: I want to buy a Buffalo Nickel for my U.S. Type Set. The only criteria are condition and the degree of detail in the well-struck coin. Money is no object. What coin would you recommend?
If money is no object and the only goals are maximum condition and the strongest strike, the coin I would recommend is:
Best Choice
1913 Type 1 Buffalo nickel (Philadelphia) in the highest available Mint State—MS67 or better.
Why this coin
1. Fresh hubs and early dies produced exceptional detail.
The first year of issue often produced the sharpest strikes in the entire series, because dies were new and had not yet worn down. Many of the finest 1913 coins show crisp hair detail, sharp braid lines, and complete buffalo horn definition—details that are frequently weak on later coins.
2. The design still had full sculptural depth.
Later die preparation and production adjustments tended to soften some details to extend die life. Early strikes preserve Fraser’s original high-relief design more completely.
3. Top-population examples show extraordinary detail.
Gem examples of the 1913 Type 1 can display virtually prooflike definition of fur texture and portrait detail, making them among the most visually impressive Buffalo nickels.
What to look for
Even within high grades, strike quality varies widely. Select a coin with:
Collectors often emphasize the horn because Buffalo nickels frequently show weak striking even in uncirculated condition. (Buffalo Nickel Club)
Why not later dates?
Buffalo nickels were notoriously difficult to strike; many examples—even Mint State coins—show weak design elements, particularly the horn and tail. (Buffalo Nickel Club)
✅ Bottom line:
For the most detailed and aesthetically impressive Buffalo nickel, pursue a 1913 Type 1 Philadelphia piece in superb Gem Mint State with a full horn and razor-sharp strike.

My '13 type 1 is an NGC MS 62. It's a great looking piece that cost me less than $50.
