The Susan B. Anthony Dollar is a coin issued by the United States from 1979 to 1981, with additional production in 1999. It features a portrait of suffragist Susan B. Anthony on the obverse and an eagle landing on the moon on the reverse, symbolizing the achievements of American women. The coin is a bi-metallic design composed of a copper-nickel alloy and is known for its distinctive similarity in size to the quarter, which sometimes leads to confusion in circulation. The 1980 coin has particular significance as it was part of an effort to produce a dollar coin that would be widely accepted and used.
