1999 Lincoln Cent--Overstruck 50% Off Center on a 1999-P Roosevelt Dime--MS-68 (NGC).This is one of the most dramatic double denomination errors that we have ever had the privilege of bringing to auction. A properly struck Roosevelt dime accidentally found its way into a cent press, where it received a 30% off center impression at 1 oclock. The obverses are aligned, but the dime design is near completely upside down in relation to that of the cent. Bold traces of both designs are evident on both sides, although the only date that is present is that of the cent, leaving us to wonder how NGC determined the date and mintmark of the dime. Bright, brilliant and virtually pristine, there is much to recommend this coin to the advanced Mint error enthusiast.
