CU-1C-1982-09 Rim Cud

Description

Ninth in the census and the second rim cud documented for 1982 Philadelphia (after entry 05, which appears on the Zinc Large Date), CU-1C-1982-09 is assigned to the Bronze Large Date subtype. The rim cud classification indicates a die break confined to the coin's outermost edge, producing a narrow raised irregularity along the border rather than the broader featureless mass characteristic of interior cuds. Having rim cuds documented on both the bronze and zinc compositions within the same census offers a potential window into comparative die failure patterns: if rim-confined breaks are proportionally more common on one composition, it could suggest that planchet material properties influence the type of rim stress that leads to fracture. No secondary cross-references have been assigned. The Bronze Large Date cent, struck from 95% copper planchets at 3.1 grams, represents the established production norm that prevailed at the start of 1982 before the historic transition to copper-plated zinc changed the Lincoln cent forever. CU-1C-1982-09 was confirmed as distinct from all eight preceding entries through careful geometric analysis. Attribution by Cuds on Coins.
