1982 (P) Lincoln Memorial Cent - Zinc Large Date - CU-1c-1982-55(LD) Cud

Description

On the zinc side of CU-1c-1982-55(LD), this specimen at 2.5 grams on the copper-plated zinc planchet with the wider large date numerals records the same interior die fracture on the post-transition composition. The paired documentation at census number fifty-five follows the established pattern of dual-composition cataloging that has defined the subtype-specific series from its inception: a die fracture discovered on one alloy composition triggers a search for — and frequently confirms the existence of — the same break on the other composition, yielding the Bronze/Zinc pairs that constitute the organizational backbone of the 1982 Philadelphia cud census. On the zinc planchet, the thin copper shell electroplated over the zinc core fills the die void with layered material whose surface presents the familiar copper tone of a Lincoln cent while concealing an interior metallurgy fundamentally different from the solid bronze fill of the paired entry. The transition zone where plating bridges from intact design to the raised cud plateau can exhibit diagnostic micro-textures under magnification — subtle stretching, thinning, or micro-cracking of the copper layer as it drapes over the abrupt geometric change. This entry awaits independent cross-referencing from external attribution systems. Attribution by Cuds on Coins.
