CU-1C-1980-02 Cud
Error
Description
Designated CU-1C-1980-02 by Cuds on Coins, this variety records the second confirmed terminal rim failure on 1980 Philadelphia Lincoln Memorial cents. The catalog notation indicates no secondary cross-reference number has been assigned, distinguishing it from CU-1C-1980-01, which carries the legacy LC-80-1A designation. The absence of a legacy number suggests this variety was documented after the Cuds on Coins catalog had transitioned to its standardized numbering system. Rim cuds on Philadelphia cents from 1980 onward are visually distinguishable from their pre-1980 counterparts by the presence of the P mintmark — a detail that aids in confirming the coin's mint origin when the cud's location does not obscure the mintmark area. The underlying die failure mechanism remains consistent regardless of mint: cyclic stress from high-speed coining operations accumulates fatigue damage at the die rim until a crack propagates to completion and a fragment separates. CU-1C-1980-02 occupies its own unique position along the die rim, and accurate attribution requires comparison against the full sequence of documented 1980 Philadelphia cuds. The 1980 Philadelphia cent was struck from the standard 95% copper alloy. Attribution by Cuds on Coins.
