Many people have appeared on the $1 coin, including President Dwight D. Eisenhower, Susan B. Anthony, Sacagawea and George Washington. Starting in 2007 the United States Mint started releasing four new $1 coins every year featuring US Presidents. This is called the Presidential $1 Coin Program.
Sacagawea was the young Indian who traveled with the famous explorers Lewis and Clark on their exploration of the Louisiana territory. Susan B. Anthony was one of the main figures in the women's suffrage and rights movement during the 19th century. In 1866, she was involved in the founding of the American Equal Rights Association.
