NGC 25c Washington Quarter on Dime Planchet & Uniface Obverse MS64

NGC Washington quarter struck on a clad dime planchet, and with a uniface obverse.

The wrong planchet error occurred when a dime planchet was fed into the press with a quarter planchet on top of it. It was then struck resulting in a coin with no design on the obverse but a struck reverse, and also the weight and metal of a dime.
