1978 Lincoln Cent--Overstruck on a 1978 Roosevelt Dime--MS-65 (NGC).Brilliant silver-gray surfaces with full mint luster and virtually all elements of the Lincoln cent design bold. The Roosevelt dime undertype is also appreciable, and it includes an identifiable date with the digits 197 readily evident and the 8 faint, yet discernible. Double denomination errors are scarce and eagerly sought irrespective of which two types they involve.From the John Whitney Walter Collection.
