Catalog Notes: The Mercury dime series doesn’t have many absolute semi-key dates, but those that it does boast are very challenging issues by every measure. The 1921 is one such piece, with the third-lowest mintage among regular issues in the series and even smaller pool of survivors.

1921 Mercury dimes are very scarce across the board, though can be had for a price in the circulated grades. Above XF to AU, this piece becomes rare, and they’re very rare in the uncirculated grades. Beware of counterfeits and cleaned specimens posing as higher-grade pieces.

The 1921 Mercury dime has a story similar to many other United States Mint issues from that year; a minor recession reduced the need for much new coinage, and any production effort at the US Mint was focused on producing new silver dollars (of which there were two types in 1921: Morgan and Peace). Thus, the majority of series in 1921 saw low mintage figures, including the Lincoln cent.

Both the 1921 and 1921-D Mercury dimes are very scarce. In the wake of the mentioned recession, no dimes were made in 1922, with production resuming in 1923.
About CDN Prices:
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.
