The U.S. Mint released the Mark Twain $1 Silver Coin in 2016 as part of the Mark Twain Commemorative Coin Program. The program includes a $5 gold coin and $1 silver coin to commemorate author Mark Twain, born Samuel Langhorne Clemens. Each coin has distinctive obverse and reverse designs that are emblematic of the life and legacy of the author.
The silver obverse (heads) design features a portrait of Mark Twain smoking a pipe with the smoke forming a silhouette of Huck Finn and Jim on a raft in the background.
The silver reverse design features an assortment of characters leaping to life from Mark Twain's works: the knight and horse from A Connecticut Yankee in King Arthur's Court, the frog from The Celebrated Jumping Frog of Calaveras County, and Jim and Huck from Adventures of Huckleberry Finn.
