The obverse features George Washington facing left, based on a 1786 bust by Jean-Antoine Houdon, while the reverse displays unique designs representing each of the 50 U.S. states, released in the order of statehood ratification. Designed by John Flanagan/Donna Weaver. Struck in 90% silver, 10% copper, weighing 6.3 grams, 24.3 mm in diameter, with a reeded edge. Cataloged as PCGS #913038. The 50 State Quarters Program (1999-2008) was the most successful numismatic program in U.S. The program revitalized coin collecting in America.
