CU-1C-1977-14 Cud

Description

Cataloged as CU-1C-1977-14 by Cuds on Coins with additional cross-references to LC-77-3A and JCc-77_31 (dated 05/08/2017), this cud variety is the fourteenth documented rim break on 1977 Philadelphia Lincoln Memorial cents. The presence of multiple cross-reference designations indicates that this particular die break has been independently documented by more than one attribution service or researcher, lending additional confidence to its cataloging. Cuds form through the complete separation of a die rim fragment — a catastrophic failure event in which a section of hardened tool steel detaches under the cyclic stress of repeated striking, leaving a void that fills with planchet metal on each subsequent coin produced by the damaged die. The raised, featureless mass of copper that results is one of the most immediately recognizable error types in numismatics. Philadelphia's 1977 production run reached approximately 4.47 billion cents, an enormous output that demanded continuous rotation of die pairs through high-speed presses. The fourteen documented cuds for this date reflect the inevitable toll of that massive production campaign. CU-1C-1977-14 is distinguishable from the other entries in the census by its specific break location and geometry, and the cross-references to LC-77-3A and JCc-77_31 provide alternative lookup paths for researchers working with different catalog systems.
