Description
CU-1C-1980-07 is a cud on the 1980 Lincoln Memorial cent. Every working die had a finite service life determined by the interplay of die steel hardness, striking pressure, planchet hardness, and production speed. When any of these variables shifted — harder planchets, higher press speeds, or slightly softer die steel from a particular batch — the rate of die failures could increase noticeably. CU-1C-1980-07 documents one such failure event, preserved in copper when the broken die continued to operate after the rim segment separated. No secondary cross-reference has been established for this variety. The 1980 Philadelphia cent was struck from the standard 95% copper alloy. Attribution by Cuds on Coins.
