The Presidential $1 Coin Program is part of an Act of Congress, enacted December 22, 2005, which directs the United States Mint to produce $1 coins with engravings of relief portraits of U.S. Presidents on the obverse. In 2007, the U.S. Mint introduced the new Presidential Dollar Coin Series, an extensive collection that celebrates each non-living U.S. President on a unique golden Dollar coin. A limited number of Presidential Dollars have been set aside from circulation. Few will have the opportunity to own these Brilliantly Uncirculated coins.
