CU-5c-1978D-01A Cud

Description

First documented cud position on the 1978 Denver Mint Jefferson Nickel at its earliest die stage, CU-5c-1978D-01A is cross-referenced as JNC-78D-2A in the Jefferson Nickel Cud census. The "2A" designation places this variety at census position 2 in its initial die stage, distinguishing it from CU-5c-1978D-01B on the same die at a later stage. A rim cud forms when a section of the die at the rim fractures completely away, creating a void that fills with metal during subsequent strikes. The 1978-D is a common date in the Jefferson Nickel series, struck in quantities exceeding 300 million pieces, and the die consumption required to produce that volume meant many die pairs saw service throughout the year. Tracking the progression from stage A to stage B on this die allows collectors to observe how the rim fracture developed over continued use — stage A captures the break at its most compact, while stage B reflects further deterioration. Together, the A and B stages for this cud provide a paired record of die failure that is useful for understanding the mechanics of rim fractures on mid-1970s nickel production.
