1/4 Dollar 'Washington Quarter' Wyoming

Wyoming entered the 50 State Quarters program in 2007 as the 44th state admitted to the Union — a sequence the program followed with deliberate historical fidelity. The series, authorized by the 50 States Commemorative Coin Program Act of 1997, was conceived partly as a revenue mechanism: the U.S. Mint calculated that collectors and hoarders pulling coins from circulation would generate hundreds of millions in seigniorage, a projection that proved accurate, with estimated profits exceeding $3 billion over the program's run.

Philadelphia and Denver both struck the Wyoming issue in 2007, with combined mintages running into the hundreds of millions.
