1964 (D) Lincoln Memorial Cent - CU-1C-1964D-02 Cud

Description

Listed as CU-1C-1964D-02 in the Cuds on Coins reference, this is the second cataloged cud variety for the 1964-D Lincoln Memorial Cent. Each cud represents a unique die failure event: a section of the die rim broke away during production, leaving a cavity that filled with metal under striking pressure to create a raised, featureless blob on the finished coin. The position, shape, and size of a cud are determined by the specific fracture pattern in the die steel, making every cud variety essentially one-of-a-kind in its geometry. Because the broken die fragment is permanently lost once it separates, a cud is an irreversible failure — the die cannot be repaired and must eventually be removed from service. This urgency may have extended the service life of marginally damaged dies beyond what would have been tolerated under normal production schedules. Cud varieties are actively collected as a specialized sub-field within die variety numismatics, with the Cuds on Coins project maintaining a systematic catalog organized by denomination, date, and mint mark. Struck on a 95% copper and 5% zinc planchet weighing 3.11 grams at 19.05 mm diameter.
