CU-1C-1971S-07 Cud

Description

Seventh cud in the 1971-S Lincoln Memorial cent catalog, CU-1C-1971S-07 documents a business strike die that fractured at the rim late enough in the Cuds on Coins numbering sequence to indicate that the 1971-S date produced a substantial population of cud-bearing dies — at least seven distinct rim breaks cataloged from San Francisco's business strike production. The gap between CU-04 and CU-07 in this batch reflects entries CU-05 and CU-06 being addressed in other documentation rather than absent from the catalog. Rim die breaks accumulate as the die processes increasing volumes of planchets, and the 1971-S cent production at San Francisco generated sufficient striking volume to push multiple dies past their structural limits at the rim. CU-1C-1971S-07's specific break location — its clock position on the coin's circumference, the angular span of the affected area, and the depth of the missing die fragment — distinguishes it from the six preceding entries and constitutes its unique diagnostic fingerprint within the catalog. Cuds on Coins' systematic documentation of these rim failures provides collectors with a reference framework for attributing specimens discovered in circulation, rolls, or accumulations of 1971-S cents. The business strike format means these cud-bearing coins entered commerce alongside normal 1971-S cents, and the raised featureless blob at the rim serves as the most immediately recognizable feature distinguishing a cud from other die failure types — unlike die cracks or die chips that modify existing design elements, cuds completely replace a section of the design with blank raised metal where the die surface itself was absent.
