CU-1C-1982D-28 Cud

Description

Twenty-eight documented cuds for the 1982-D Large Date Bronze Lincoln Cent is a remarkable total revealing how many Denver Mint dies experienced rim fractures during this transitional year's bronze production. Each cataloged cud represents a distinct working die with an independent rim failure, and the progression from the second to the twenty-eighth charts a long sequence of documented deterioration events. The 1982 transition from 95% copper to copper-plated zinc required Denver to run both compositions, and the bronze planchets' hardness relative to zinc created specific mechanical stresses on dies. A cud forms when a rim section fractures and separates completely, leaving a cavity that fills with metal during striking to produce a raised featureless mass at the coin's edge. Twenty-eight cuds suggests Denver's bronze cent production consumed enough die pairs — and pushed them through enough striking cycles — to generate failures at a rate that kept researchers discovering new entries over an extended period. Cataloged by Cuds on Coins, this twenty-eighth entry documents widespread die rim failure across the final months of bronze cent production at Denver.
