1968-S Doubled Die Reverse DDR-004

Description

Struck during the first year that proof production moved to San Francisco, DDR-004 on the 1968-S Proof Roosevelt Dime displays a medium spread across UNITED STATES OF AMERICA and a lighter spread on ONE DIME. The reverse die variety is classified as RDV-002, distinguished by a strong flame element in the torch design. Cataloged as FS-802, this variety carries UVC-522 and DMR-013 attribution codes. Three die stages have been identified: Stage A in early die state (unconfirmed), Stage B showing both reverse and obverse at mid-die state, and Stage C in late die state (unconfirmed). Prior to 1968, proof coins had been struck at Philadelphia, making San Francisco proofs from this inaugural year particularly significant to collectors tracking the transition. Doubled die proofs combine the sharply mirrored fields of proof coinage with the hub-doubling anomaly — a pairing that enhances the visibility of the displaced design elements against the reflective proof surface.
