野牛镍币
First struck in 1913, the Buffalo nickel had long been difficult to coin, and after it completed the 25-year term during which it could be replaced only by Congress, the Mint moved quickly to replace it with a new design. The Mint conducted a design competition, in early 1938, requiring that Jefferson be depicted on the obverse and Jefferson's house Monticello on the reverse. Schlag won the competition, but was required to submit an entirely new reverse and make other changes before the new piece went into production in October 1938.
