CU-1c-1982-09(LD) Rim Cud

Description

Cataloged as CU-1c-1982-09(LD), this rim cud on the Zinc Large Date subtype documents a peripheral die fracture on the lighter 2.5-gram copper-plated zinc planchet paired with the wider date numerals. As a rim cud, the die break remained confined to the outermost edge of the die face — the narrow zone where the working die meets the retaining collar — producing a raised metallic strip along the coin's periphery rather than the broad featureless plateau characteristic of interior cuds. The subtype-specific numbering system that governs this entry functions as a secondary catalog within the broader 1982 Philadelphia cud census: where the sequential numbering (CU-1C-1982-01 through -85) assigns each die break a unique position regardless of subtype, the subtype-specific series (CU-1c-1982-XX with lowercase "c") organizes entries by their alloy and date punch combination, allowing researchers to analyze die failure patterns within each of the four Philadelphia subtypes independently. This zinc version forms one half of a Bronze/Zinc pair sharing the same census designation, meaning the fractured die operated across the mid-1982 composition changeover and imprinted its peripheral break on both planchet materials.
