B-2, BB-20 [R1]. Nice, original coin with old-time coloration (x NGC VF25).
1795 Flowing Hair Silver Dollars are known in two different major varieties: 2 Leaves and 3 Leaves. To determine the variety, simply look at the leaf clusters beneath the eagle's wings -- the clusters will contain either two or three leaves.
In terms of relative rarity, the 2 Leaves variety is approximately three times as rare as the 3 Leaves variety. Mint State examples of both major varieties are rare and valuable. Surprisingly, the PCGS Condition Census is comprised entirely PCGS MS64 and better examples. The best examples are a pair of PCGS MS65s
