This is the third year that the Mint produced Native American Dollars. The 2009-S Proof Native American Dollar has the same obverse design that was used on 2000 Sacagawea Dollars. However, in 2009 the Mint began using different reverse designs on the coins and referred to them as Native American Dollars instead of Sacagawea Dollars. The 2011-S Proof Native American Dollars came in proof sets from the year. Most coins came in very nice quality ranging from about PR68-PR70 Deep Cameo. PR70 Deep Cameo coins were much more difficult to find but enough examples have been found to keep prices affordable.
