CU-1C-1981-13 Rim Cud

Description

Distinguished by its rim cud classification, CU-1C-1981-13 documents a die break specifically confined to the outermost edge of the 1981 Philadelphia Lincoln Memorial cent. Rim cuds differ from standard cuds in their geometry — where a typical cud can extend inward from the rim to obliterate portions of the design field, a rim cud follows the coin's peripheral boundary, producing a narrow raised strip rather than a broad featureless blob. This confinement to the rim edge reflects a fracture that propagated along the die's outer margin without extending into the interior design area, suggesting a failure mode driven primarily by edge-loading forces rather than the broader compressive stresses that generate larger interior breaks. CU-1C-1981-13 is the thirteenth confirmed cud variety in the 1981 Philadelphia census, and its rim-confined geometry required particularly careful documentation to distinguish it from nearby entries whose breaks may approach but not replicate its specific edge profile. As the penultimate year of copper cent production, the 1981 Philadelphia cent was struck from 95% copper alloy weighing 3.1 grams and bears the P mintmark. Attribution by Cuds on Coins.
