The new dollar coin was heavily marketed by the Mint in a series of print, radio, and television advertisements, as well as Mint partnerships with Walmart and Cheerios. However, the Sacagawea dollar did not prove popular with the public, and mintage dropped sharply in the second year of production. Production of Sacagawea dollars continued, from 2007 to 2016, in parallel with the U.S. Presidential dollars. In 2012, mintage numbers were reduced by over 90%, in line with a similar reduction for the even less popular Presidential Dollars, due to large stockpiles of unused coins from that series.
