CU-1c-1982-19(LD) Cud

Description

Entering the upper teens of the subtype-specific Large Date catalog, CU-1c-1982-19(LD) on the Zinc Large Date subtype documents an interior cud at 2.5 grams on the copper-plated zinc planchet with the wider date numerals. The progression from CU-1c-1982-01(LD) through -19(LD) traces nearly two dozen unique die fracture geometries cataloged specifically within the Large Date subtype — a count that reflects the extraordinary number of working dies that served this configuration during Philadelphia's 1982 production. Each entry in this progression represents a distinct die whose rim failed in a unique way, confirmed through photographic comparison against every preceding entry to ensure no duplication. The verification rigor increases with each new submission: at census depth nineteen, a candidate must be differentiated from eighteen existing entries on the same subtype, requiring precise angular measurement of the fracture's position relative to design landmarks and careful assessment of the break's radial extent. The zinc planchet's lighter weight and distinct metallurgical character make this half of the Bronze/Zinc pair readily distinguishable from its heavier bronze counterpart by precision scale alone.
