1971-S Doubled Die Reverse DDR-001

Description

Holding the premier catalog position for Kennedy Half Dollar proof doubled die reverses from 1971-S, this DDR-001 was documented by VarietyVista with Universal Variety Code UVC-195, Die Marriage Record DMR-017, and the Cherrypickers cross-reference FS-801 — a Fivaz-Stanton listing that signals recognition as a significant variety worthy of inclusion in the standard cherry-picking reference guide. The doubling presents as medium spread on the eagle's feathers, lower shafts of the arrows, HALF DOLLAR, and the stars above those letters, with light spread on OF AMERICA and the designer's initials. The die stage record spans three phases: Stage A with both reverse and obverse in Early Die State, Stage B at Mid Die State (unconfirmed), and Stage C with both in Late Die State. The VarietyVista comments specify this is a proof variety with the obverse designated ODV-002, linking the reverse to a specific obverse design variety that establishes the complete die marriage context. The 1971-S Kennedy Half Dollar proof was struck at the San Francisco Mint in the Kennedy Half Dollars Clad and Silver Proof 1971 to Date series. As the first cataloged DDR for this date-mint combination and a Cherrypickers-listed variety (FS-801), this represents one of the highest-profile Kennedy proof varieties in the early clad/silver proof era. The FS-801 designation specifically draws cherry-picking collectors to this variety as an identifiable variety with established market recognition, and the medium spread across the eagle design and denomination inscriptions provides sufficient visual impact to make confirmation straightforward under moderate magnification.
