CU-1C-1979D-04 Cud

Description

Designated CU-1C-1979D-04 by Cuds on Coins, this variety documents the fourth confirmed rim break on 1979 Denver Mint Lincoln Memorial cents, with the gap from the first entry indicating that CU-1C-1979D-02 and -03 exist elsewhere in the catalog. Four documented cuds for a single Denver date places the 1979-D among the more productive years for terminal die failures at that facility, though the count remains consistent with expectations for a high-mintage date operating large numbers of die pairs at production speed. Each cud variety in the census originates from a separate working die that reached the failure threshold — the point at which accumulated fatigue damage along the rim culminates in the detachment of a steel fragment. The diagnostic for distinguishing CU-1C-1979D-04 from the other entries lies in the specific rim location of the break, the angular arc it spans, and any design elements obscured by the resulting extrusion of copper. Denver's hand-punched D mintmark appears on the obverse of all 1979-D cents and can sometimes interact with cud breaks if the failure occurs in the vicinity of the date or mintmark area, though each variety's specific break position must be confirmed against reference photographs. All 1979-D Lincoln Memorial cents were struck from the standard 95% copper alloy composition. Attribution by Cuds on Coins.
