Three Cent Silvers Complete Variety Set, Circulation Strikes (1851-1872)

This is our smallest coin. It's also the only one struck in 75% silver (that's the "type one" of 1851-53 only). There are lots of tiny mintages in the series, many condition rarities, three different types and a lot of history. Why does the set stop in 1872? Because the 1873 is a "Proof-only" issue with no circulation strikes being issued. One more bit of trivia: Only one date in the series has a mintmark. Can you name the date and Mint?

Notes: This set is a work in progress. This set is a work in progress. As new varieties are recognized, they may be added to the set. Likewise, delisted varieties will no longer be required.
