Lewis Feuchtwanger produced a metal that was really a variety of German silver consisting of nickel, copper, and some zinc. He suggested to Congress as early as 1837 that his metal be substituted for copper, and he made one-cent and three-cent trial pieces that circulated freely during the coin shortage of 1836 through 1844.
