1971 (S) Proof Jefferson Nickel - Doubled Die Reverse DDR-001

Description

Holding the primary DDR designation for the 1971-S Jefferson nickel, DDR-001 exhibits light spread on STATES OF AMERICA, PLURIBUS UNUM, and the right building edge of Monticello with the spread increasing from left to right — a rotational spread pattern indicating the secondary hub impression was displaced at a slight angle relative to the primary. VarietyVista assigned identifiers UVC-1392 and DMR-009, and the comments note that the reverse employs RDV-006 (strong railings), a reverse design variant distinguished by particularly prominent railing detail on Felix Schlag's Monticello depiction. Significantly, the obverse die of this pair is listed as DDO-001, meaning this die marriage carries both the primary obverse and primary reverse doubled die designations — an uncommon dual attribution that makes specimens from this die pair especially interesting to variety collectors. The rotational increase in spread from left to right across the reverse inscriptions is characteristic of a pivot-point displacement where elements closer to the rotation axis show minimal doubling while those further away exhibit progressively greater separation. The strong railings designation (RDV-006) provides an independent confirmation feature — collectors can verify the reverse die identity by examining the railing detail on Monticello before proceeding to evaluate the doubled die diagnostics. Magnification of 15-20x should be directed at the right building edge and the letters of STATES OF AMERICA, where the progressive increase in spread is most evident.
