The United States Mint has released concept artwork of the designs selected to represent Presidents Truman, Eisenhower, Kennedy, Johnson, and Nixon. The first four designs (Truman through Kennedy) will be struck in 2015, the remaining two are scheduled for 2016.
Since 2007, in accordance with Public Law 109-145, also referred to as the Presidential $1 Coin Act of 2005, the United States Mint has produced four dollar coin designs per year honoring each of the Presidents of the United States starting with George Washington. The program is scheduled to come to an end in 2016 with the release of the Ronald Reagan Presidential dollar.
After the Reagan coin is struck, several living presidents will be absent from the set as living Presidents are prohibited from appearing on United States coins. In the event that a living past or current President dies during the program, the law calls for a 2-year moratorium on the production of a coin bearing that President's likeness.
The living former Presidents are Jimmy Carter, George H. Bush, Bill Clinton, and George W. Bush.
