About Twenty Cent Pieces CAM [Type] 20-Cent Pieces (Proof)
Proof versions of the 20 cent coin were issued for the brief period these coins were struck, from 1875 through 1878. While the "double dime," designed by William Barber, proved quite unpopular with much of the public, proofs were struck by the Philadelphia Mint during each of the four years the denomination was in production.
In 1877 and 1878, the last two years the 20 cent series was struck, only proofs were made, with 510 of the former date and 600 of the latter. Today, the 1877 and 1878 proof-only 20 cent coin are highly scarce and valuable, as they are sought after by collectors who wish to assemble date runs of the short-lived series. The 1875 and 1876 proofs, with 1,150 of the earlier and 1,200 of the latter, are the most common proof specimens.
Cameo and deep cameo proofs as well as pieces with brilliant fields are the scarcest proofs and command strong premiums over standard prices. However, all proof 20 cent coins are scarce and treasured numismatic relics.
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.
