The American twenty-cent piece is a coin struck from 1875 to 1878, but only for collectors in the final two years. Proposed by Nevada Senator John P. Jones, it proved a failure due to confusion with it being the same size and value of the quarter Source: Wikipedia
There were also a small number of 1875 S "proofs" I think it may have the right rev die, but that rev was used on three different varieties. I can't be sure because the image isn't good enough (There is another very similar rev used two other varieties.) and there is also no image of the obverse.
