CU-5c-1970D-01C Cud

Description

Cataloged as CU-5c-1970D-01C by Cuds on Coins and cross-referenced in the Jefferson Nickel Cud catalog as JNC-70D-1C, this rim cud on a 1970 Denver Mint Jefferson Nickel documents a progressive die stage — the "C" suffix indicating a specific state of the die crack's evolution as the fracture widened through continued use. When a section of the die rim fractures completely away, the resulting void fills with metal during striking to produce a raised, featureless mass along the coin's edge. Tracking die stages through suffixes like A, B, and C allows researchers to reconstruct the chronological progression of die deterioration from initial fracture through final failure. The 1970-D Jefferson Nickel is a common date in the series, but documented die varieties with multiple tracked stages are less frequently encountered and provide useful data about the die life cycle under production conditions. The JNC cross-reference integrates this variety into the broader Jefferson Nickel Cud census, which systematically catalogs rim cuds across all dates and mints in the series.
