1/4 Dollar 'Washington Quarter' Olympic National Park, Washington

The Olympic National Park quarter was the 56th release in the America the Beautiful Quarters Program, which Congress authorized in 2008 as a successor to the 50 State Quarters series. Olympic National Park in Washington state is unusual among U.S. national parks in encompassing three distinct ecosystems within a single boundary — temperate rainforest, subalpine terrain, and a wild Pacific coastline — a combination that shaped why it received UNESCO World Heritage designation in 1981.

Philadelphia and Denver struck circulation strikes; San Francisco produced collector versions in both clad and 90% silver proof. The silver proof issues from San Francisco are the only 90% silver Washington quarters struck for any purpose since 1964.
