CU-1C-1982-32 Rim Cud

Description

Third rim cud on the Zinc Large Date subtype within the 1982 Philadelphia census, CU-1C-1982-32 joins entries 12 and 17 in the rim-confined category. The recurrence of rim cuds at this frequency — three out of the first thirty-two entries for this single subtype — suggests that peripheral die fractures were a meaningful failure mode at Philadelphia during 1982 zinc cent production. A rim cud's confinement to the die's outermost margin may indicate failure driven primarily by collar-related stresses rather than the broader radial forces that produce interior cuds. The distinction matters for die failure analysis: collar interactions create a specific load pattern at the die rim that differs from the compressive forces distributed across the striking face, and dies that fail at the rim rather than the interior may be responding to different metallurgical or mechanical conditions. Struck from copper-plated zinc planchets weighing 2.5 grams, this coin belongs to the post-transition phase of Philadelphia's 1982 production. The 1982 composition changeover from 95% copper bronze to zinc-core blanks created the most complex single year in Lincoln cent history, with seven recognized varieties across three mints.
