1971-S Doubled Die Obverse DDO-006

Description

Paired with a specific reverse die hub variety, DDO-006 on the 1971-S Proof Jefferson Nickel shows light spread on IN GOD WE TRUST and carries Reverse Die Variety RDV-006, identified by its strong railing detail on Monticello's portico. Die markers UVC-1398 and DMR-015 confirm this working die. The RDV-006 designation refers to a reverse hub that produced particularly well-defined railings along the stairs and balustrade of Felix Schlag's Monticello rendering — an architectural detail that varies noticeably across different reverse die hubs due to progressive hub wear and periodic re-engraving. The strong railings characteristic is independent of the obverse doubling: RDV-006 identifies the reverse die hub origin, while DDO-006 identifies the obverse working die's hub misalignment. This pairing means a single coin carries two independently collectible variety attributes. As a proof coin struck at the San Francisco Mint, this nickel was produced on polished planchets and sold exclusively through annual proof sets in standard copper-nickel composition. The proof surface quality aids detection of the light spread on IN GOD WE TRUST by providing mirror fields that maximize contrast with any secondary letter images. Collectors should verify both the obverse motto doubling under magnification and the reverse railing detail — the strong railings are typically visible to the unaided eye when compared against a weak-railing reverse die variety.
