1971-S Doubled Die Obverse DDO-019

Description

A proof variety from the San Francisco Mint, the 1971-S Kennedy Half Dollar DDO-019 displays a medium spread on IN GOD WE TRUST, the date, and the Y of LIBERTY — with the Y showing independent doubling direction from the other affected elements. Cataloged by VarietyVista as UVC-252 with die marriage reference DMR-018, the obverse die is further identified as using the ODV-003 obverse die variety, connecting it to a specific hub lineage in the Kennedy Half Dollar die family. Three die states are tracked: Stage A in early die state is unconfirmed, Stage B at mid-die state is characterized by a small die gouge in the hair above Lincoln's — rather, Kennedy's — forehead with the reverse also in mid-die state, and Stage C in late die state remains unconfirmed. The 1971-S Proof Kennedy Half Dollar was struck at the San Francisco Mint during the clad composition era, and proof doubled die varieties from the early 1970s are actively sought by Kennedy Half specialists. The ODV-003 designation adds a layer of attribution depth, as collectors interested in die variety classification can track which hub variety was used in the die's manufacture alongside the doubled die characteristics that developed during the hubbing process.
