WRONG PLANCHET MINT ERROR COINS

Off metals and wrong planchet errors occur when a blank from one denomination is accidentally fed into a press for another denomination. The coin struck on an incorrect blank will weigh exactly what the denomination of that blank would have been. These dramatic British Royal Mint coins have been independently authenticated and certified by PCGS as genuine mint error coins. These are 20 pence coins struck on 5 pence planchets.
