Anthony appeared on the obverse of the new dollars in 1979. No other woman's portrait (not imagined or mythical) had ever been struck on any U.S. coin. From 1981-1998 the U.S. Mint stopped issuing these dollars. One of the reasons the coins were never popular was due to their reduced size. From 1840-1978 all dollars measured 38.1 mm, while the new Susan B. Anthony coin measured 26.5 mm, only two millimeters bigger than the popular quarters. Susan B. Anthony dollars have a pure copper inner core and an outer layer made of 75% copper and 25% nickel, each weighs 8.1 grams. Susan B. Anthony dollars were coined at the Philadelphia, Denver and San Francisco Mints.
