CU-1c-1982-04(LD) Cud

Description

Documented as CU-1c-1982-04(LD) on the Zinc Large Date subtype, this cud records a die rim failure on the post-transition copper-plated zinc planchet weighing 2.5 grams, paired with the wider large date numerals. The "(LD)" suffix in the census designation explicitly identifies the date punch style, distinguishing this entry from any small date counterpart that might share the same census number. The Zinc Large Date represented one of Philadelphia's primary production configurations during the second half of 1982, after the copper-plated zinc blanks had fully replaced the bronze planchet supply. Dies that struck this subtype were working a softer, lighter planchet than the bronze stock they may have originally been designed for — a materials change that could subtly alter the distribution of striking pressure across the die face and potentially influence where rim fractures initiate. This zinc version of CU-1c-1982-04(LD) is paired with a bronze counterpart under the same census number, documenting the same die break across both alloy compositions. The zinc planchet's lower density and different elastic properties mean the displaced metal filling the die void has a subtly different character than on the heavier bronze version.
