CU-5c-1970D-01A Cud

Description

Documenting the earliest known die stage of the first cud position on a 1970 Denver Mint Jefferson Nickel, CU-5c-1970D-01A cross-references as JNC-70D-1A in the Jefferson Nickel Cud census. The "A" suffix indicates this is the initial recorded state of the rim fracture, capturing the cud at its smallest and least developed stage before continued striking enlarged the break. Die stage tracking is essential for understanding how rim fractures evolve — the same die progresses through stages as the separated area grows and the cud becomes more prominent on subsequently struck coins. A rim cud forms when a portion of the die rim cracks completely away, and the void fills with metal during each strike to produce a raised, blank mass. Collectors pursuing die stage sets for a single variety seek specimens from each documented stage, effectively reconstructing the die's deterioration in sequence. The 1970-D is a common date in the Jefferson Nickel series, but documented cuds with tracked die stages provide variety specialists with material that goes beyond simple date collecting into the study of die life and failure patterns.
