Twenty-Cent Piece

The United States twenty cent coin (often called a twenty cent piece) was a unit of currency equalling 1/5th of a United States dollar. The twenty cent coin had one of the shortest mintages and lowest circulations in US coin history, for both the series and the denomination. It was minted from 1875-1878, but was only released for circulation in 1875 and 1876, with only a few hundred proofs released during the remaining two years. - Wikipedia.org
