Following the popular 1999-2009 Statehood Quarters program, the United State Mint is issuing commemorative quarters with special reverse designs celebrating national parks and other national sites. From 2010 through 2021, a park or site is being honored in each of the 50 states and 6 territories. Each national park or site was selected for its natural or historical significance. The 56 different designs are featured on the reverse side of the coin and are representative of the unique character and environment of the national park or historic site. The obverse side of the coin features a smaller restoration of the original washington quarter portrait, modeled from designer John Flanagan's 1932 plaster.

This Littleton national parks quarter folder Vol.2 holds quarters of 2016 through 2021, both D and P one coin each, total 60 quarters.
