In 2010, the United States Mint launched the America the Beautiful Quarters® Program, a 12-year initiative with 56 quarter-dollar coins featuring reverse designs depicting some of our most cherished national parks and other national sites. Under this program, the United States Mint will issue five new quarter designs per year, with one final design in 2021. The third year of the program, 2012, features the third five quarters in the series.
With each coin struck in lustrous 90 percent silver, also known as “coin silver,” the 2012 edition of the United States Mint America the Beautiful Quarters Proof Set features the third release of five quarters in the America the Beautiful Quarters® Program.
In 2012, the sites being featured are El Yunque National Forest in Puerto Rico, Chaco Culture National Historical Park in New Mexico, Acadia National Park in Maine, Hawai’i Volcanoes National Park in Hawaii and Denali National Park and Preserve in Alaska. Each quarter bears the “S” mint mark of the United States Mint at San Francisco.
