1971-S Doubled Die Obverse DDO-016

Description

Light spread on IN GOD WE TRUST, the date, and TY of LIBERTY marks the 1971-S Proof Kennedy Half Dollar DDO-016 — a San Francisco proof variety from the year proofs returned to this denomination after the 1970-D was the last 40% silver business strike. Attributed by VarietyVista as UVC-364 with die marriage DMR-020, all three die states are documented and confirmed: EDS, MDS, and LDS for both obverse and reverse — an uncommon completeness in die state documentation. The obverse is classified as ODV-003, and the proof designation indicates this variety was struck with specially prepared dies and polished planchets for inclusion in proof sets. The 1971-S proof Kennedy Half Dollar was struck in the copper-nickel clad composition, transitioning away from the 40% silver content of earlier proof issues. Collectors tracking complete die state progressions find this variety well-documented across its full production arc.
