As the silver coins recovered from the Civil War-era ship SS Republic® were being examined, a rare 1860-O die-error Seated Liberty Silver Half Dollar was discovered. This mint error was made by the original die-makers at the New Orleans Mint and found its way onto a small percentage of coins that were struck that year. The "High O" error can be identified by the "O" mintmark being misplaced too high. A quick check of authentication records revealed that NONE had ever been certified by NGC before this discovery! Die errors like these can literally multiply the value of a coin.
