CU-1C-1966-12 Cud

Description

Recorded as CU-1C-1966-12, this twelfth cud variety for the 1966 Lincoln cent continues to expand the catalog of die rim failures from this peak-production year. The process of documenting and cataloging cud varieties is an ongoing endeavor driven by a dedicated community of error and variety specialists. The Cuds on Coins project, which attributed this variety, maintains a systematic catalog of cud die breaks across all U.S. coin denominations, assigning sequential designations within each date and denomination to create a comprehensive reference. For the Lincoln cent series, the cataloging prefix CU-1C indicates a cud (CU) on a one-cent coin (1C), followed by the date and a sequential number within that date. This standardized nomenclature allows collectors and researchers to reference specific varieties unambiguously and to track the growth of the catalog over time as new discoveries are reported. The 1966 cent was produced at the Philadelphia Mint without mint marks, consistent with the Coinage Act of 1965 mandate. The year's mintage of 2,188,147,783 business strike cents was supplemented by 2,261,583 Special Mint Sets produced at the Philadelphia Mint, though SMS coins are cataloged separately from business strikes due to their different striking characteristics and finish. Cud varieties on 1966 cents are exclusively from business strike dies, as the SMS production used a smaller, more carefully monitored die population. Cross-referenced as CU-1C-1966-12 and attributed by Cuds on Coins. Struck on a 3.11-gram, 19mm planchet of 95% copper and 5% zinc.
