1956 Doubled Die Reverse DDR-006

Description

Revealing a progressive Class V pivoted doubling pattern, DDR-006 on the 1956 Philadelphia Jefferson Nickel exhibits light spread on E PLURIBUS UNUM and AMERICA that increases in intensity from left to right across the affected inscriptions. Die markers UVC-923 and DMR-010 confirm this working die. The left-to-right intensification is the signature of pivoted hub doubling, where the secondary hub impression was rotated slightly around a pivot point located to the left of the affected text. Letters nearest the pivot axis show minimal offset, while letters farther from it display progressively greater displacement — creating a gradient that serves as both a mechanical fingerprint and an authentication diagnostic. On Felix Schlag's Monticello reverse, E PLURIBUS UNUM and AMERICA curve in arcs above the building, and the progressive spread across these inscriptions produces a visually measurable intensification that collectors can trace letter by letter from left to right. The 1956 nickel was struck in standard copper-nickel composition (75% copper, 25% nickel) at the Philadelphia Mint without a mintmark. DDR-006 sits within a deeply documented set of 1956 reverse varieties — at least ten doubled die reverses have been cataloged for this date — reflecting the thorough attention variety researchers have devoted to mid-1950s Jefferson Nickel production. Light intensity means the progressive spread requires careful magnified examination to trace.
