The 2008-D Sacagawea Dollars have one of the lowest mintages if not the lowest in the entire series. The coins were released on April 28, 2012. They are common in grades up to MS66. In MS67 some sorting is required but not difficult to find with proper searching. In MS68 they are very difficult to find and probably no more than 100 examples exist in this condition or higher.
