Counting All Coins: Dollars

Susan B. Anthony Dollar obverse and reverse
On July 2, 1979, the U.S. Mint issued the Susan B. Anthony dollar coin. It replaced the Eisenhower Dollar. This was the first time that a woman, other than a mythical figure, appeared on a circulating coin. The coin is inscribed on the obverse (the head side) with: Liberty, In God We Trust, and the date. The reverse shows an American eagle landing on the Moon, an adaptation of the Apollo 11 insignia. The inscriptions on this coin are: United States of America, E Pluribus Unum (which means "out of many, one"), and One Dollar. This coin was legislated on October 10, 1978 under the presidential term of Jimmy Carter. 

Susan B. Anthony was born February 15, 1820 in Adams, Massachusetts. She was brought up in a Quaker family with long activist traditions. Early in her life she developed a sense of justice and moral zeal.

After teaching for fifteen years, she became active in temperance. Because she was a woman, she was not allowed to speak at temperance rallies. This experience, and her acquaintance with Elizabeth Cady Stanton, led her to join the women's rights movement in 1852. Soon after, she dedicated her life to woman suffrage.

Ignoring opposition and abuse, Anthony traveled, lectured, and canvassed across the nation for the vote. She also campaigned for the abolition of slavery, the right for women to own their own property and keep their earnings, and she advocated for women's labor organizations.

In the 1890s Anthony served on the board of trustees of Rochester's State Industrial School, campaigning for coeducation and equal treatment and opportunity for boys and girls. She raised $50,000 in pledges to ensure that women would be admitted to the University of Rochester. In a last-minute effort to meet the deadline, she put up the cash value of her life insurance policy. The University admitted women for the first time in 1900.

Susan B. Anthony had a keen mind and a great ability to inspire. She remained active until her death on March 13, 1906. Read more and see photos of her home at

The Dollar Coin Act of 1997 provided for a new dollar coin to be placed into circulation when supplies of the Susan B. Anthony dollar coin were exhausted. This coin honored Sacagawea, the young Shoshone woman who was a  huge help to the Lewis and Clark expedition. The Sacagawea Dollar was first issued in 2000. Here's the 2005 version:
