1971 (S) Lincoln Memorial Cent - CU-1C-1971S-07 Cud

Description

CU-1C-1971S-07 is a cud on the 1971-S Lincoln Memorial cent. 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. 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.
