20th Century Proof Type

关于此套币: I absolutely love proof coins, who doesn't? From the Barber coinage, to the infamous Mercury dime, proof coins give a detailed specimen of each [proof] coin made from 1900 to 1999. I started this set with the Mercury dime and I plan to end it with the Morgan dollar. I hope you enjoy this set as much as I do and see how far I can progress! Enjoy. [Set started 2/22/21]
