野牛镍币
A commission run by the Federal Council of Churches in America sought issuance of a half dollar to mark the anniversary, and the bill passed through Congress without opposition in 1923 and was signed by President Warren G. Harding. Sketches were prepared by commission chairman Reverend John Baer Stoudt and converted to plaster models by the Mint's aging chief engraver, George T. Morgan. The models were initially rejected by the Commission of Fine Arts, which required revisions under the supervision of Buffalo nickel designer James Earle Fraser.
