CU-5c-1972D-01 Cud
Error
Description
First in a remarkably prolific sequence of documented cuds for the 1972 Denver Mint Jefferson Nickel, CU-5c-1972D-01 cross-references as JNC-72D-2B in the Jefferson Nickel Cud census. The "2B" designation places this variety at position 2 in the census die stage B, distinguishing it from other cuds at different rim locations or stages on the same date. A cud forms when a piece of the die rim fractures and separates completely, and the void fills with metal during striking to produce a raised mass at the edge. The 1972-D is one of the most productive dates for documented Jefferson Nickel cuds — multiple catalog entries spanning different rim positions testify to the number of dies consumed during this date's production run. Denver's substantial nickel output in 1972 placed heavy demands on die pairs, and the mechanical stresses of high-volume striking increased the statistical likelihood of rim fractures across the many dies employed. Each cud documents a unique die, since a rim fracture is a terminal event that ends the die's useful life within a relatively short span. Cataloged by Cuds on Coins.
