How much are my U.S. 1990 No S with red surfaces penny worth?

About 1990 No S RD Lincoln Cents - Memorial Reverse (Proof)

A very unusual variety surfaced in 1990 when a few dozen examples of the 1990 Lincoln proof cent appeared without its requisite S mintmark. As the months turned into years, only a handful of other 1990 no S proof cents surfaced, proving this variety to be an especially rare error indeed. In an era of tight quality control at the United States Mint, it seems unfathomable that an error of this type, one in which a San Francisco Mint proof coin is missing its mintmark, could have ever been created, let alone was able to escape the mint. Yet, it did.

In all, fewer than 200 examples of the 1990 no S proof Lincoln cent have been discovered. On rare occasions, one still turns up in an unsearched hoard of 1990 proof sets. Whether or not many more exist remains to be seen, but it is without a doubt one of the rarest and most significant of all modern proof varieties and demand remains strong for this sensational error.

About CDN Prices

All CDN prices are based on proprietary market knowledge and technology developed by CDN Publishing, LLC.

CPG® prices represent retail levels. Collectors should refer to CPG values as a starting place for their negotiations, or auction bid reference.

Greysheet/Greensheet prices are wholesale market levels for collectible coins/paper money intended to indicate what a dealer, or wholesale, buyer would pay for the described item in the specified grade. Greysheet/Greensheet represent "sight-seen" values based on a buyer's in-hand review. The actual value can be more or less than this depending on factors including eye appeal and market timing.

Bluesheet (NGC & PCGS) prices represent the highest sight-unseen offers to buy on dealer networks like CDN Exchange. In many cases, there are no active sight-unseen buy offers, so CDN looks to the recent lowest market values for such an item. For this reason, Bluesheet values typically represent the floor of the market for the specified item. CDN only tracks Bluesheet on certain items.

CAC prices are for U.S. coins that meet the standards of the Certified Acceptance Corporation. You can learn more about CAC on their web site.

Price movement is indicated for price changes in the last 30 days.

The values listed are only indications. CDN Publishing, LLC does not buy or sell collectibles.
