From 1979 to 1981, and again in 1999, the Mint produced Anthony Dollars, depicting Susan B. Anthony, the first non-fictitious woman portrayed on circulating U.S. coinage. (Many earlier circulating coins featured images of women, but the women depicted were all non-specific representations of Liberty. Spain's Queen Isabella was portrayed on the 1893 Columbian Exposition quarter dollar, but it was not intended as a circulating coin, although some did circulate.)  The Anthony dollars, like the Eisenhower dollars, were made from a copper-nickel clad. The 1981 coins were issued for collectors only, but occasionally show up in circulation.
