Description
Fourth in the Philadelphia 1975 cud census, CU-1C-1975-04 documents another terminal rim break on a die that produced Lincoln Memorial cents at the Philadelphia Mint without a mint mark during 1975. Cataloged by Cuds on Coins, this variety carries no additional cross-reference numbers from other attribution systems. The cud error is created when fatigue-driven crack propagation through the die steel reaches a critical threshold, causing a section of the rim to fracture and separate entirely from the working die face. The void left behind fills with planchet metal during each subsequent strike, and the resulting raised, textureless mass is reproduced identically on every coin produced by the damaged die until it is detected and replaced. CU-1C-1975-04 is distinguished from the other cataloged Philadelphia 1975 cuds by its specific rim position and the design elements it affects or obliterates, and precise comparison against reference images is essential for definitive attribution.
