CU-1C-1970S-07 Cud

Description

Skipping CU-06 in the numbering sequence, CU-1C-1970S-07 documents the seventh cataloged cud variety for the 1970-S Lincoln Memorial cent on a Large Date business strike. The gap at CU-06 suggests that either a sixth cud was cataloged but subsequently delisted or reclassified, or that the numbering reflects a broader system where CU-06 may be assigned to a different date or denomination. Regardless of the gap, CU-1C-1970S-07 represents another distinct die fracture from San Francisco's 1970 cent production — a working die that developed a break at or near the rim, allowing a fragment to separate and creating the characteristic void that produces a raised, featureless mass on every subsequent strike. The accumulation of seven numbered cud varieties (plus the reverse cud CU-03R) for the 1970-S date places it among the more productive cud-producing date-mintmark combinations in the Lincoln Memorial cent series. Each entry documents a unique die failure event with its own fracture geometry, angular position, and penetration depth — a catalog of mechanical failures that collectively narrate the physical demands San Francisco's coining presses placed on their working dies during 1970 production.
