CU-1c-1974-17 Cud

Description

Carrying the catalog designation CU-1c-1974-17, this cud is cross-referenced as JCc-74_14 in the JC cud catalog, with a documentation date of October 1, 2013. The dual catalog presence — in both the Cuds on Coins and JC systems — provides collectors with independent verification of this variety and multiple reference points for locating it in the numismatic literature. This is the seventeenth cataloged cud for the 1974 Philadelphia Mint Lincoln Memorial cent, a count that reflects the extraordinary scale of die consumption at Philadelphia during this production year. Approximately 4.23 billion cents left Philadelphia in 1974, all struck without a mint mark, and the dies that produced them endured hundreds of thousands of high-pressure impacts each before being retired. Rim fractures — where accumulated fatigue drives a crack through the die steel until a section of the rim separates entirely — were among the inevitable consequences of running dies at this intensity and volume. The separated fragment leaves a cavity at the die's edge, and planchet metal filling this cavity produces the raised, amorphous blob that defines the cud error type. Seventeen documented cuds from a single Philadelphia date constitutes an impressive census by any measure, and the JCc-74_14 cross-reference for CU-1c-1974-17 indicates that this variety was significant enough to warrant formal documentation in multiple independent catalog systems. Collectors attributing this variety should verify both the Cuds on Coins and JC catalog entries for consistent positional data.
