CU-1C-1967-06 Cud

Description

Recorded as CU-1C-1967-06, this sixth cud variety for the 1967 Lincoln cent illustrates how high-volume production environments create statistically fertile ground for die failures of every kind. When the Philadelphia Mint produced 3,048,667,100 business strike cents in 1967, the die population required to sustain that output numbered in the thousands of pairs, and each die pair experienced its own unique trajectory of wear, deterioration, and eventual failure. Some dies developed rim cracks early in their service life due to metallurgical imperfections or alignment irregularities; others lasted hundreds of thousands of strikes before cumulative fatigue finally triggered a fracture. The diversity of cud varieties cataloged for 1967 — varying in size, position, and the extent to which they encroach on the design — reflects this range of die failure histories. For collectors building a set of 1967 cud varieties, each new addition represents a distinct die whose specific service history is encoded in the shape and location of the cud. The 1967 date was the last year without mint marks on U.S. coins, as the Coinage Act of 1965's three-year mandate expired at the end of the year and mint marks were restored beginning in 1968. Cross-referenced as CU-1C-1967-06 and attributed by Cuds on Coins. Struck on a 3.11-gram, 19mm planchet of 95% copper and 5% zinc.
