1971-S Doubled Die Obverse DDO-009

Description

With die markers UVC-1720 and DMR-049, DDO-009 sits well into the upper range of documented 1971-S proof Jefferson Nickel obverse dies — a high DMR number reflecting the extensive die population produced for this proof issue and the thorough cataloging effort across dozens of distinct DDO varieties within a single date-mint run. Light spread manifests on LIBERTY, the star, the date, and designer's initials FS. The reverse die is RDV-006, identifiable by strong railings on Monticello. What distinguishes DDO-009 from lower-numbered counterparts is the unique die marker combination: UVC-1720 identifies surface characteristics exclusive to this working die, while DMR-049 points to extensive diagnostic documentation. Each 1971-S proof DDO variety represents a separate working die carrying the same general hubbing displacement but its own individual die fingerprint. Attribution requires matching both the obverse doubling pattern and specific die markers under magnification.
