Each set contains five coins which honor Gettysburg National Military Park in Pennsylvania, Glacier National Park in Montana, Olympic National Park in Washington, Vicksburg National Military Park in Mississippi and Chickasaw National Recreation Area in Oklahoma.

Struck at the San Francisco Mint in a copper-nickel clad composition, each set comes in its original mint box with certificate.

United States proof coins are extraordinarily brilliant, with sharp relief and a mirror-like background. Their frosted, sculpted foregrounds give them a special cameo effect. Proof blanks are specially treated, polished and cleaned to ensure high quality strikes. The blanks are then fed into presses fitted with hand-polished dies and struck at least twice to ensure sharp relief. The coins are then packaged in presentation cases to showcase and maintain their exceptional finish
