CU-1c-1982-17(LD) Rim Cud

Description

Classified as a rim cud, CU-1c-1982-17(LD) on the Bronze Large Date subtype records a die fracture whose break geometry remained confined to the coin's outermost peripheral band — the third rim cud designation in this batch, joining CU-1c-1982-09(LD) and -12(LD) in the peripheral fracture category. The recurrence of rim cuds at regular intervals throughout the subtype-specific catalog reflects a consistent mechanical reality: at any given time during production, some fraction of active dies will develop fatigue cracks at the collar interface rather than at interior stress concentration points, producing peripheral breaks rather than design-field disruptions. On the Bronze Large Date planchet at 3.1 grams, the rim cud's narrow raised strip traces a segment of the coin's edge in solid 95% copper alloy, its warm reddish tone continuous with the surrounding intact rim design. Rim cuds demand more careful examination than interior cuds because their visual footprint is smaller and more easily confused with post-mint rim damage — the key diagnostic being the flat, die-struck quality of the raised metal versus the irregular, mechanically deformed profile of contact damage from coin-counting machines or roll storage.
