CU-1c-1982-39(SD) Cud

Description

Representing the lighter-weight counterpart under census number CU-1c-1982-39(SD), this zinc specimen at 2.5 grams on the copper-plated zinc planchet with the compact small date numerals shares the cross-references LC-82 SD-3 Cu and JCc-82_14SD with its bronze twin. The existence of confirmed cross-references on both halves of a Bronze/Zinc pair strengthens the documentary foundation for this die break considerably: where a single cross-reference might reflect a tentative correlation, dual independent verification across both alloy compositions indicates that catalogers in the LC and JCc systems examined specimens from both sides of the mid-1982 composition transition and recognized them as products of the same fractured die. On the zinc planchet, the thin copper coating over the zinc core creates a layered fill within the cud region, and the boundary where plating bridges from intact design surface to the raised featureless plateau can reveal micro-textures under moderate magnification that differ from the bronze version's homogeneous fill. The 2.5-gram weight provides the fastest diagnostic for separating this entry from its 3.1-gram paired member, while the compact date numerals must be confirmed visually against large date examples to complete the subtype identification.
