Interesting observation

We all know that Ian/GC is a huge advertiser with PCGS. Most all of us know that the late Stewart Blay's coins are being sold.

It's interesting to note that the 1984 Doubled Die Obverse FS#102 Lincoln Cent (of which an MS65 example from Stewart is being auctioned at GC right now) went from a value of $350 to a value of $1,750 in the PCGS price guide in December, 2022 (consignment time for Stewart) without any sales to justify such an increase.

In fact the only published sale on PCGS of this variety is an NGC MS67 example sold by Heritage in Jan of 2017 for $194.

Interesting, right?

Not really.

Had your thread merely been about the uptick in price with no new public sale, then perhaps it was interesting. However, given the conspiracy theory bent of your thread to suggest that a $1,400 increase in a single, obscure coin might be tied to the sale of a six-figure (or more, who knows?) collection seems like there was an obvious agenda to the thread.

I see these type of price changes (without apparent data) semi-regularly. Below is from the PCGS price guide page and makes note of what can be used to influence the price guide. I do know of dealers who have submitted data to get a price changed. Perhaps you could also with the proper information / data behind it.

IMPORTANT

The PCGS Price Guide prices apply only to PCGS-graded coins. The PCGS Price Guide is a guide to assist the coin buying public in determining values for all important United States rare coins. Before you use the Price Guide, you should read the following information very carefully.

WHAT DO PCGS PRICES MEAN?

The prices listed in the PCGS Price Guide are average dealer asking prices for PCGS-graded coins. The prices are compiled from various sources including dealer ads in trade papers, dealer fixed price lists and website offerings, significant auctions, and activity at major coin shows. Dealer specialists and expert collectors provide pricing input. Remember that the prices are just a guide, a starting point for asserting value. Some PCGS coins sell for less than the prices listed and some PCGS coins sell for more than the prices listed.

I can see where you are coming from, however there are far more prices to be considered than just the ones pcgs (publicly) tracks. It's possible they track outside auction sales as well beyond the dozen or so big guys that aren't listed in the recent sales data. The sales of low population coins really are worth whatever someone is willing to pay... The price guide is just that. A guide. I wouldn't read too much into any of it personally.
