1971-S Doubled Die Reverse DDR-010

Description

A proof variety from the San Francisco Mint, the 1971-S Kennedy Half Dollar DDR-010 displays a light spread on UNITED STATES OF AMERICA, HALF DOLLAR, and the stars surrounding the heraldic circle — a broad distribution of doubling across the reverse legend and design elements. Cataloged by VarietyVista as UVC-569 with die marriage reference DMR-034, the obverse die is classified as ODV-002, connecting this variety to a specific hub lineage shared with other 1971 Kennedy Half varieties. Stage A confirms both reverse and obverse in early die state, while Stages B and C remain unconfirmed in mid and late die states respectively. The 1971-S Proof Kennedy Half Dollar was struck at the San Francisco Mint in copper-nickel clad composition for inclusion in annual proof sets, and proof specimens provide the optimal viewing conditions for evaluating light-spread doubled die varieties, as the mirror fields and sharp strikes characteristic of proof production render subtle hub doubling more visible than on circulation strikes. The high die marriage number — DMR-034 — indicates this was the thirty-fourth documented die pairing for the 1971-S date, reflecting the extensive variety population discovered on proof Kennedy Half Dollars from this era.
