CU-1C-1975D-03 Cud

Description

Third in the 1975 Denver Mint cud catalog, CU-1C-1975D-03 records yet another rim break on a die that was used to strike Lincoln Memorial cents at the Denver facility during 1975. Each entry in a date's cud census represents a distinct die that developed a terminal rim fracture — the point at which accumulated stress caused a section of hardened die steel to break free from the die's edge. The detached fragment left a cavity that filled with flowing planchet metal on every strike, creating the raised, textureless mass that characterizes cud errors. Three documented cuds from a single date-mint combination begins to illustrate the scale of die consumption inherent in the Denver Mint's mid-1970s cent production. With billions of cents required annually, die pairs were cycled through the presses at a relentless pace, and some percentage inevitably developed rim fractures before being pulled from service. CU-1C-1975D-03 occupies its own unique clock-position on the die rim, distinguishable from both CU-1C-1975D-01 and -02 by the specific location and extent of its break. No additional cross-reference numbers have been assigned to this variety beyond its Cuds on Coins catalog designation. Attribution by Cuds on Coins.
