A rare issue with perhaps a few hundred struck that year without the S mintmark on the cent. This example has radiant red color, deep frost on the devices and rose to lilac toning on Lincoln when closely examined. NGC has seen 16 this fine and just 15 a point finer for this elusive and important mint error.
