Most commonly remembered for its unpopularity within circulation, the Susan B. Anthony Dollar was minted during four years. The first three years of mintage were from 1979 to 1981, and following a lengthy gap in production, the final year of the series was 1999. The obverse of the coin features a portrait of the famous women’s suffragist and the reverse features an image of the eagle landing on the moon after the Apollo 11 mission insignia. The designer of the coin was Frank Gasparro.
In size, the Susan B. Anthony Dollar was between the quarter dollar and half dollar. This caused confusion within circulation when the coins were reportedly often confused with the quarter. After the short duration of the series, the US Mint would create an entirely new composition and color for the following Sacagawea Dollars, in an attempt to differentiate the coins better within circulation.
