Susan B. Anthony dollar

The Susan B. Anthony dollar coin is a coin minted between 1979 and 1981, and again in 1999. It depicts women's suffrage campaigner Susan B. Anthony. The reverse depicts an eagle flying above the moon, a design adapted from the Apollo 11 mission insignia that was also present on the previously issued Eisenhower dollar. Though it is round, it may appear 11-sided, due to an 11-sided rim bordering the edge of both sides.

Because of their mutually approximate size and color, it is very easy to mistake for a quarter. It was unpopular and was disparagingly referred to as the "Carter quarter" or the "Anthony quarter." Although not used much in circulation, it was accepted by some vending machines, including those of the United States Post Office and mass transit in large cities. The coin was re-issued in 1999 when the US Mint's supply of dollar coins was exhausted, before it was possible to start production of the gold-colored Sacagawea dollar released in 2000. Approximately 910 million Anthony dollars were produced during their four years of issue.

The Anthony dollar is notable by numismatists because (as of 2005) it was the last coin produced for regular issue by the San Francisco Mint.

From 2000 through 2004, the Susan B. Anthony Dollar circulated along with the Sacagawea dollar. The Presidential $1 Coin Act of 2004 would have changed this, as it proposed taking all remaining Susan B. Anthony Dollars out of circulation. This bill did not pass, and the SBA Dollar therefore remains in circulation along with the Sacagawea dollar as of 2005.
