1977 Lincoln Memorial Cent - CU-1C-1977-09 Cud

Description

Ninth in the sequence of documented rim breaks on 1977 Philadelphia Lincoln Memorial cents, CU-1C-1977-09 extends the cud census cataloged by Cuds on Coins. Every cud tells a story of mechanical failure — a working die, subjected to the immense pressures of the coining press, develops a fatigue crack at its periphery that eventually isolates a fragment of rim steel. Once the fragment separates, the die's effective striking surface is permanently altered: where the rim once existed, there is now a void that fills with planchet metal on each strike, producing the characteristic raised blob. CU-1C-1977-09 carries no additional cross-reference numbers beyond its Cuds on Coins catalog designation, placing its attribution exclusively within that system. Collectors should reference the catalog's photographic documentation for precise die-break location when confirming specimens. Attribution by Cuds on Coins.
