1974 (D) Lincoln Memorial Cent - CU-1C-1974D-06 Rim Cud

Description

Cataloged as CU-1C-1974D-06 by the Cuds on Coins attribution service, this rim cud variety is the sixth documented cud for the 1974 Denver Mint Lincoln Memorial cent. The "Rim Cud" designation in the title emphasizes that the die break occurred precisely at the die's peripheral edge — the rim — rather than as an interior die break where a fragment of the die face separates but remains partially or wholly retained within the die cavity. Rim cuds and interior die breaks are mechanistically related (both result from fatigue-driven fracture of die steel), but they produce distinctly different appearances on the finished coin: a rim cud, the loss of part of the die's rim gutter, appears as a raised interruption in the design rim that tracks the rim's course, while a retained interior break typically shows a raised area surrounded on all sides by normal design elements. The die responsible for CU-1C-1974D-06 failed at a specific point along its circumference that distinguishes this variety from all others in the 1974-D cud census. As with all cud attributions, the primary diagnostic criteria are positional: the angular location of the break on the coin, the arc-length of the missing rim segment, and the specific design elements beside the break.
