The obverse features George Washington facing left, based on a 1786 bust by Jean-Antoine Houdon and the reverse displays unique designs representing each of the 50 U.S. states, released in the order of statehood ratification. California, Minnesota, Oregon, Kansas, and West Virginia. Satin finish specimens from mint sets were produced. As a proof issue, this coin was struck multiple times on specially prepared polished planchets using polished dies, producing mirror-like fields and frosted design elements prized by collectors.
