The America the Beautiful quarters (sometimes abbreviated ATB quarters) were a series of fifty-six 25-cent pieces (quarters) issued by the United States Mint, which began in 2010 and lasted until 2021.^[1] The obverse (front) of all the coins depicts George Washington in a modified version of the portrait used for the original 1932 Washington quarter.^[2] There were five new reverse (back) designs each year (one in 2021), each commemorating a national natural or historic site such as national parks, national historic sites, or national forests – one from each state, the federal district, and each territory. The program was authorized by the America's Beautiful National Parks Quarter Dollar Coin Act of 2008 (Pub. L.Tooltip Public Law (United States) 110–456 (text) (PDF).
