1/4 Dollar 'Washington Quarter' George Rogers Clark National Historical Park, Indiana - Silver 5 oz Bullion

The George Rogers Clark National Historical Park commemorates Clark's 1779 winter campaign against the British-held Fort Sackville at Vincennes — a campaign conducted through flooded bottomland in February, with men wading chest-deep for days before the garrison surrendered. Clark's victory effectively secured American territorial claims to the Northwest Territory, land that would eventually become five states.

This five-ounce issue belongs to the America the Beautiful bullion series authorized under the America's Beautiful National Parks Quarter Dollar Coin Act of 2008. The KM#666 designation marks the bullion strike, distinct from the collector burnished version issued the same year.
