1795 Half Dimes are relatively scarce as type coins go and there are several varieties (see below) that are quite rare. However, as scarce as they might be, 1795 Half Dimes are easily obtained in Mint State, including in Gem condition. This is also one fo the few early U.S. type coins that can be found in MS67 condition.
