LITTLETON-America The Beautiful Commemorative Quarter Folder Volume I: 2010-2015. Following the popular 1999-2008 Statehood quarters program and one-year 2009 D.C. and U.S. Territories quarters program, the United States Mint is issuing commemorative quarters with special reverse designs celebrating national parks and other national sites. From 2010 to 2021, a park or site is being honored on each of the 50 States, the District of Columbia and five U.S. Territories: Puerto Rico, Guam, American Samoa, U.S. Virgin Islands and Northern Mariana Islands. Each national park or site was selected for its natural or historical significance. Coins struck for general circulation bear a P (Philadelphia) or a D (Denver mint mark signifying where the coins were produced. This exclusive Littleton folder provides individual labeled spaces for each coin produced in both Philadelphia and Denver from 2010 to 2015. Made in USA.
