1978 (D) Lincoln Memorial Cent - CU-1C-1978D-08 Cud

Description

CU-1C-1978D-08 was cataloged by Cuds on Coins with the notation "number: none," indicating no additional cross-reference designations from other attribution services. The cud formation mechanism is consistent across all instances: fatigue cracks nucleate at stress concentration points along the die rim, propagate through the hardened steel with each successive striking cycle, and eventually reach critical length, at which point a segment of the rim detaches entirely. The damaged die continues to operate until a press operator detects the anomaly, and during that interval, every coin struck receives the characteristic raised mass of extruded metal at the break location. All 1978-D cents bear Denver's hand-punched mintmark and were struck from the standard 95% copper alloy. Attribution by Cuds on Coins.
