Best Of

Sorry but I can already see that this will be a little long .

I see a couple comments on not including GC in the pcgs auction and/or price results. This is also true for Greysheet. However, this comment I believe should be directed towards GC as they do Not release their auction records in bulk to anyone. Therefore, as I understand it, to use the data would require going to GC website and pulling individual results and not being able to necessarily link to the auction result information. Heritage and Stacks and others do allow their results to be 'bulk' used and therefore are seen in the auction records of other sites like pcgs and greysheet/CDN.

@winesteven Now look what you did. j/k
Many of the CDN values now (emphasis on now) do not agree with the numbers you quoted above. Why? Well an example is below. These are the wholesale CAC.

$2000 change to $2200 on 11/25/25 and then change on 11/28/25 (today for this post) to $5500. with a CAC CPG $6250.
It appears many others other than the ones you mentioned were also updated.

@winesteven Yes, your post on the greysheet or CDN versus CPG is correct. This is for both the CAC and non-CAC.
Greysheet defines their CPG to be a proprietary formula (or factor) based off of their greysheet (wholesale) value to generate a CPG (retail) number. Typically this value ranges from around 1.35 times the greysheet (wholesale) for lower value coins to about 1.20 times the greysheet (wholesale) value for higher priced coins. As CDN states when the greysheet (wholesale) value is changed the CPG (retail) value will change with it. This is done independently for CAC and then non-CAC coins.

Next perhaps another question to ask is why should different price guides agree? One answer might be when they represent the same thing. But then how the prices are determined could also generate differences.

Looking at what the pcgs and greysheet represent:
PCGS states that their price guide represents:
"The prices listed in the PCGS Price Guide are average dealer asking prices for PCGS-graded coins."
From: https://www.pcgs.com/prices
This does Not distinguish between pcgs non-cac and pcgs cac. In some cases this difference could be small at 10% or less. But in other cases it could be much larger at 50% or 100% (twice as much) or maybe even more on select cases. Also the average dealer asking prices in some cases could be somewhat iffy.

CDN - greysheet does distinguish between non-cac and cac approved coins where such coins are available. However, CDN does not distinguish between NGC and PCGS for cac approved or not cac approved. Similar to the pcgs non-cac versus pcgs cac, the difference between an NGC and PCGS or NGC cac and PCGS cac can be small at 10% or less. But again sometimes the difference can be much larger (50% or 100% twice as much) and this for similar coins not some special toned coin or similar.

I will also note that, as I recall, John F has stated somewhere in a video as I recall, that CDN will typically error on the side of a lower price guide value when data is limited or there is a divergence of the data.

So from this, these two price guides might not be representing the same thing.

@EastonCollection
You mentioned/asked why did pcgs lower the price on the 10c 1827 MS66.
Perhaps another question to ask is why did CDN also lower the price? Here is the information on that and these are CAC greysheet (wholesale).
Oct 2019 $24,000.
Oct 2020 $20,000.
June 25, 2025 $27,500.
Nov 25, 2025 $16250. (with CPG $19500) ********* price reduced
Nov 28, 2025 $17,380. with CPG $21,000.

Like winesteven's above the value was updated today (as of this post) to a slightly higher value compared to the OP.
So why did both price guides reduce the value?
I don't know but could a bid have been pulled or something similar?
The most recent auction record I see is for a non-cac NGC from SB 8/13/24 at $12,000. which CDN could use for their non-cac valuation. Could this impact the perceived CDN cac approved value? I don't know.

@TrickleCharge
Yes, the pcgs auction prices realized has not done well in recent years. It is more than just the sorting. Since about 2023 pcgs auction prices realized has been generally slow to post auction results and they are also not posting as many auction results as in years past. Currently the last Heritage auction results are from July 2025 and Stacks Sept 2025 (and if one tracks eBay those are Aug 2025). Don't know if anything has changed for access to Goldbergs, Scottsman and DLRC but those have not been included since 2023. Additionally the number of auctions included from particularly Heritage but also Stacks has gone down. It is now mainly the more significant auctions whereas previously the included some of the weekly auctions or specialty auctions.

I don't have a photo, I have been watching the live ebay channels, still learning, On Whatnot which is very similar, I won a 1 oz silver round for 30 bucks plus 4 bucks shipping.... Just testing the waters..

I also saw a 1877 cc dime in horrible condition go for hundreds of dollars!! Ouch

I am by no means advocating for these new auctions, just learning.

@jmlanzaf Yes, the document @habaraca is exactly what I have. So it's apparently what you sent me and I just retained it. You did yeoman's work on that file; it's 30 some pages long! And I am surely happy to give you credit for your work.

Thanks. I don't need credit but I just wanted to make sure we all had the same one.

I also have hundreds of pages of FBI files from a FOIA request. Bonnano was under constant surveillance. I find no evidence to support the story. They were aware of a number of criminal enterprises but there no mention of minting equipment or gold. There was something about smuggling in wheels of cheese that made me laugh.

I have a 35 page (!) pdf from 1-31-18 with what I think are TTTT's comments in the original Omega thread. I see where there are responses to posts by others but their posts are not included. I guess I just collected TTTT's contributions. While I think TTTT's comments were a crock, if you want a copy of this pdf pm me your email and I'll send it.

Is that the one I sent? I had compiled it in January 2018 and sent it to a few people. [See below]

To revive a long dead thread, did anyone happen to save this PDF which is no longer available:

http://www.chemgod.com/ebay3/I actually do have some information on the Omega Man.pdf

(Also not available on web.archive.org of that site)

Thanks

That was my document. I changed hosting. I can email it to you if you pm me with an email address

Great coins, fellas !!

@MrEureka - I got to admit, you shared on this thread one of favorite Capped Bust dimes of all time - its a 1827 JR-10 SP. Its absolutely fabulous! I saw that coin several years ago and I get chills thinking about it! Thank you for adding to my Thanksgiving!
@winesteven - Thank you for pointing out another series where prices are very different between price guides!

I do realize that pricing coins that are traded frequently are easier than less frequently traded coins and I do realize that frequently traded coins with great strike, high eye appeal and/or exceptional toning trade above price guides. We all get it and even novice collectors get it in short order. If the major price guides price out a coin around $3,000 and if collector or dealer wants to pay alot more, than its on them, not on the price guide.

Pricing is an art and not a science. We all get that too.

Many dealers and collectors are stating that price guides aren't either up to date or just plain wrong. I would like those that publish price guides to get it right by enhancing their QC, have support for their prices, incorporate the experts in the specific series in determining prices and incorporate all prices realized from auctions and shows and all other information and knowledge out there. I really don't think that I am asking that much........

@Eddi . Thank you and wow. Great collection, makes my entire morning. james

When did you place it? If it was one of the last ones in, that might explain it, while everyone is looking for a HHL violation explanation.

Also, the e-mail could just be a mistake. Did you go into your order history and confirm that the order was, in fact, canceled?

All of my order(s) were made within the first 15 or so minutes of the sale start. I had multiple browsers, computers, and smartphones working. I've seen a couple of other places (ex. Son of a Silver Stacker-YouTube) mention cancelled orders for this Marine Corps Privy coin.

As to viewing the order history page, I actually had not for this particular user account but did tonight and unfortunately, it was showing cancelled there, in addition to the e-mail rcvd. Maybe it's a good thing for others that I might just be in some unlucky group of cancellations - in order to provide backup replacement coins to the big boys after they reported the issues with this Privy and were not happy that they were about to get screwed by the Mint on this issue.

All my other orders are safe as this time...let's hope it stays that way for me and everyone else.
