By 1931, Two Guns White Calf, son of the last Blackfoot tribal chief, was capitalizing off his claim to be the model for the coin. To try to put an end to the claim, Fraser wrote that he had used three Indians for the piece, including "Iron Tail, the best Indian head I can remember. The other one was Two Moons, the other I cannot recall." In 1938, Fraser stated that the three Indians had been "Iron Tail, a Sioux, Big Tree, a Kiowa, and Two Moons, a Cheyenne". Despite the sculptor's efforts, he (and the Mint) continued to receive inquiries about the identity of the Indian model until his 1953 death.
