Description
Designated CU-1C-1966-05, this is the fifth documented cud variety for the 1966 Lincoln cent, continuing the pattern of frequent die rim failures across the year's enormous production run. A cud variety is identified and distinguished from other cuds of the same date by the specific location of the rim break relative to the coin's design elements. Numismatists typically describe cud positions using clock-face notation (e.g., "at 2:00" or "between 9:00 and 11:00") and note which design elements are affected or adjacent to the cud. Because each cud results from a unique fracture event on an individual die, no two cuds are truly identical, even when they occur at similar positions — the exact arc length, depth profile, and edge characteristics of the break will differ. Cross-referenced as CU-1C-1966-05 and attributed by Cuds on Coins. Collectors searching for cud varieties in rolls or bags of 1966 cents should inspect the full rim circumference of each coin under low magnification, as even small cuds can be significant additions to the catalog. Struck on a 3.11-gram, 19mm planchet of 95% copper and 5% zinc.
