CU-1C-1982-13 Cud

Description

Cataloged as CU-1C-1982-13 in the Cuds on Coins census, this standard cud variety on the 1982 Philadelphia Zinc Large Date cent records a die rim segment that fractured completely away from the die body, leaving a void that produced a raised, featureless mass on every subsequent coin struck from the damaged die. The distinction between this interior cud and the rim cud documented one census entry earlier (CU-1C-1982-12) illustrates the spectrum of rim failure geometries that coining dies can exhibit: where rim cuds are confined to the outermost edge, standard cuds extend deeper into the design field, displacing recognizable portrait or legend elements with blank metal. Die rim fractures are driven by the cumulative mechanical fatigue of millions of striking cycles, as micro-cracks propagate through the hardened steel until a segment separates entirely. The zinc Large Date composition — 2.5 grams of copper-plated zinc — identifies this as a product of the second half of 1982, after Philadelphia completed the transition away from the heavier 3.1-gram bronze planchets. Thirteen cud entries for a single year and mint speaks to the enormous scale of Philadelphia's 1982 cent output, measured in the billions. Attribution by Cuds on Coins.
