Wyoming designated the Sacajawea golden dollar as the official state coin in 2004. Sacajawea (1788 - 1812) was a Shoshone woman who accompanied the Lewis and Clark Expedition in their exploration of the Western United States.
Historical details about Sacajawea are extremely limited, but she has become a critical character of the Lewis and Clark expedition in the American public's imagination. In the early twentieth century, the National American Woman Suffrage Association adopted her as a symbol of women's worth and independence.
The Sacagawea golden dollar coin depicts Sacagawea and her son, Jean Baptiste. The face on the coin was modeled after Randy'L He-dow Teton (a modern Shoshone-Bannock woman).
