    Undated "Silver" Eagle, MS63
    Struck on an Emery Disc

    Undated $1 Silver Eagle -- Struck on a 3M Emery Disc -- MS63 PCGS. Although the legends of this piece state it is "1 OZ. FINE SILVER," this coin contains no silver at all, since it was struck on a wafer-thin emery disc. An emery disc is thin, round, granular, and adhesive-backed. It is typically affixed to a buffing wheel, and was presumably used at the Mint to help prepare dies. Somehow, an emery disc with an unpeeled backing covered a silver eagle planchet at the moment of strike. The silver planchet (not included) blocked the obverse die, so the front of this gray-brown piece has a reverse die impression, while the other side shows an incused and reversed impression of the reverse, along with previous printing on the backing.
