1/4 Dollar 'Washington Quarter' Chickasaw National Recreation - Silver 5 oz Bullion

The Chickasaw National Recreation Area quarter was the fifth and final release in the 2011 America the Beautiful series, which itself was Congress's expansion of the State Quarters program into federal lands and national parks. The five-ounce silver bullion format — struck to the same design but at three inches across — was introduced specifically to capture the investor and collector market that had largely ignored the circulating clad versions.

The Chickasaw issue commemorates a site in southern Oklahoma that the federal government established partly to give residents of the Indian Territory access to the natural springs at Sulphur — a deliberate political gesture during Oklahoma's territorial period.
