CU-1C-1982-05 Rim Cud

Description

Fifth in the census and classified specifically as a rim cud, CU-1C-1982-05 documents a die break confined to the outermost peripheral edge of the 1982 Philadelphia Zinc Large Date cent. Rim cuds differ geometrically from standard cuds in that the fracture follows the die's outer margin without extending appreciably into the interior design area, producing a narrow raised strip along the coin's border rather than a broad featureless blob that obliterates design elements. This confinement to the rim suggests a failure mode driven primarily by edge-loading stresses — the forces concentrated at the die's periphery where the collar and die rim interact during each strike. The rim cud designation requires particularly precise documentation to distinguish it from nearby standard cuds whose breaks may approach the rim area but differ in extent and geometry. No secondary cross-references have been assigned. Struck from copper-plated zinc planchets (2.5 grams) with the Large Date punch style, this coin comes from the post-transition phase of Philadelphia's 1982 production, after the switch from the traditional 95% copper alloy.
