1971-S Doubled Die Obverse DDO-005

Description

Sharing the same three-element light spread pattern and RDV-006 strong railings reverse pairing as DDO-002, DDO-005 on the 1971-S Proof Jefferson Nickel is distinguished by its unique die markers UVC-1397 and DMR-014. The three-digit UVC gap between DDO-002 (UVC-1394) and DDO-005 (UVC-1397) indicates three intervening cataloged varieties — DDO-003 and DDO-004 — separating these two entries in the VarietyVista system, each presumably carrying its own distinct die markers and potentially different spread patterns or intensities. That DDO-005 matches DDO-002 in both affected elements (LIBERTY, star, date) and intensity (light) while carrying different die markers means attribution between the two demands examination of die-specific characteristics rather than doubling pattern alone. DMR-014 documents the unique scratches, polish lines, and flow marks on this particular working die that distinguish it from DDR-011's characteristics on DDO-002 — these are the definitive separation criteria. Both varieties' shared RDV-006 reverse pairing suggests the San Francisco Mint may have employed multiple obverse dies against the same strong railings reverse die, or that multiple reverse dies from the RDV-006 hub were in concurrent use during proof production. As a proof issue struck on polished planchets with mirror-finish dies, the reflective surfaces amplify even light spread on LIBERTY, the star, and the date. Collectors attempting to distinguish DDO-005 from DDO-002 should capture high-magnification images of any die lines or polish marks near LIBERTY and compare against published DMR documentation for each variety.
