The coins in this category are the collectible 5 oz Silver "ATB" coins which have been produced in limited quantities. The United States Mint America the Beautiful Program (ATB) is a multi-year initiative to honor 56 national parks and other national sites in each state, the District of Columbia and five U.S. territories—Puerto Rico, Guam, American Samoa, U.S. Virgin Islands and the Northern Mariana Islands. Under this program, five new designs appeared each year beginning in 2010. The highly collectible coins will be minted through 2020, with one final coin in 2021. The series features the 1932 portrait of George Washington by John Flanagan, restored to bring out subtle details and the beauty of the original model, on the obverse (heads). The reverse (tails) design depicts an image representative of one of the 56 National Parks and sites. The numismatic collectibles are produced with an uncirculated finish and display a "P" mint mark for the United States Mint at Philadelphia, where they are struck. Their fineness and weight are edge-incused on the coins.
