Due to the limited circulation of the cumbersome Eisenhower dollar, it was decided in 1977 that a smaller dollar coin might see improved circulation and prove more useful to the public. On September 26, 1978, Congress approved legislation to provide for a smaller dollar coin to be minted, which would depict Susan B. Anthony, a prominent American suffragette. These new dollars also proved unpopular, due in large part to their similarity in size and metallic composition to the quarter-dollar. Since there was little interest in the coin as a circulating medium, most were placed in United States Mint and Federal Reserve vaults throughout the country, and mintage ceased after 1981.
