1956-D Doubled Die Reverse WDDR-001

Description

Carrying the CONECA cross-reference 1-R-II-C, this primary doubled die reverse for the 1956-D Jefferson Nickel presents Class II distorted hub doubling visible as a close spread on UNUM and OF AMERICA. The CONECA (Combined Organizations of Numismatic Error Collectors of America) attribution of 1-R-II-C breaks down systematically: "1" indicates the first listed variety, "R" designates the reverse, "II" identifies the doubling class (distorted hub), and "C" provides the sub-listing. Obverse die markers include a short die gouge to the left of the I in IN, while the reverse carries a slanted die gouge between the letters L and U of PLURIBUS. Class II distorted hub doubling occurs when the hub — the master positive from which working dies are impressed — flexes or distorts between successive impressions during the hubbing process, producing design element shifts that vary in magnitude across the die face in a non-uniform pattern. The 1956-D was a high-mintage Denver Mint business strike Jefferson Nickel, produced during a period when Felix Schlag's original design was in its eighteenth year of production and die manufacturing processes were well-refined. As the -001 designation confirms, WDDR-001 is the most significant doubled die reverse for the 1956-D date, and its dual attribution through both the Wexler and CONECA systems provides collectors with robust cross-referencing capability. The die markers — particularly the gouge near the I of IN and the slanted gouge in PLURIBUS — serve as essential secondary diagnostics for attribution when the doubling itself is too close for confident identification from the spread alone.

Die Markers
