In 2016, a gold $5 half eagle and silver dollar will commemorate American author and humorist Mark Twain.

On Thursday, the U.S. Mint released a total of 59 obverse and reverse designs for the Citizens Coinage Advisory Committee to consider for possible use on the coins.

Twain authored such legendary novels asThe Adventures of Huckleberry Finn and The Adventures of Tom Sawyer.
