1968-D 10C, FB MS68FB 认证号29739677, PCGS号85134

Designer: John R. Sinnock Content: 75% Copper, 25% Nickel over a pure Copper center Weight: 2.27 grams Diameter: 17.90 millimeters Edge: Reeded Production Strikes: 480,748,280 General Type Description: Due to the increasing cost of silver, beginning in 1965, the Roosevelt dime (and quarter) underwent a composition change which eliminated its silver content. The new coin(s) would be minted from a clad “sandwich” of base metals—75% copper and 25% nickel surrounding a copper core. While the design would remain identical to the previous issues, the change in metal composition resulted in a weight reduction from 2.5 grams to 2.27 grams. Exemplar Notes: A fully-struck (“full bands”) Superb Gem acquired 2/2015 from Alan Hagar; one of only seven graded MS68FB with none finer(as of 2/2015).
