1969 (D) Lincoln Memorial Cent - CU-1C-1969D-07 Cud

Description

Bearing the designation CU-1C-1969D-07 from Cuds on Coins, this cud variety on the 1969-D Lincoln Memorial cent documents yet another terminal die failure in Denver's prolific 1969 cent production. Die steel of this era — typically high-carbon, high-chromium tool steel — was engineered to withstand hundreds of thousands of impressions, but microscopic imperfections in metallurgical structure, combined with the repetitive impact forces of high-speed coining presses, inevitably nucleate cracks that grow with each successive strike. When such a crack reaches the periphery of the die face, the unsupported fragment breaks free under the next impact, creating the characteristic cud. The 1969-D cent holds particular significance as a collectible date because Denver had only recently resumed applying its D mint mark after the three-year hiatus mandated by the Coinage Act of 1965. Collectors seeking cud varieties from this transitional period benefit from the high survival rate typical of circulated cents — many cuds passed through commerce without being noticed, awaiting discovery decades later.
