Struck from Canceled Dies. A numismatic item with raised defacing marks made from canceled dies. While usually found on medals where the issuer requests a striking made from such a die to prove the die was so canceled, it has occurred on coins. Breen illustrates a unique 1792 prototype Washington half dollar with the reverse die canceled (Breen 1346). After a single piece is struck, the die is then destroyed, melted, sold for scrap, or, very infrequently, archived. See canceled dies.
