CU-1c-1982-48(SD) Cud

Description

The zinc member of census number CU-1c-1982-48(SD) at 2.5 grams on the copper-plated zinc planchet with the compact small date numerals records the same die fracture on the post-transition composition. The Zinc Small Date, while sharing the same date numeral geometry as its bronze twin, has a distinctly different metallurgical profile that affects how the planchet material fills the die void: the layered copper-over-zinc construction means the cud's raised plateau has a thin copper shell over a zinc core, and where the strike forces the planchet into the irregular geometry of the fracture boundary, the plating may conform differently than the solid bronze alloy does. Collectors who acquire both halves of a Bronze/Zinc pair gain a side-by-side comparison of how the same die fracture manifests on two fundamentally different planchet materials — a comparison that can be instructive for understanding the relationship between planchet metallurgy and die break appearance. The 2.5-gram weight separates this specimen from the 3.1-gram bronze version, but visual date inspection remains essential for distinguishing it from the identically weighted Zinc Large Date cuds cataloged under nearby census numbers.
