The original Sacagawea dollar (KM310) was minted from 2000 to 2008. In 2009, the US Mint started an annual Sacagawea series -- the Native American Dollar Program -- with different reverse designs. The US Mint went to great lengths to encourage these coins to circulate, at least during the first three years of the program when over 200 million coins were minted.
The 2020 coin commemorates Elizabeth Peratrovich and her roll in getting the Alaskan Anti-Discrimination Act of 1945 passed into law. She was a member of the Tlingit nation -- indigenous peoples of the Pacific North-west coast of North America -- and of the Raven moiety within the Tlingit.
