1920 (S) Lincoln Wheat Cent - CU-1C-1920S-06R Rim Cud

Description

Sixth reverse cud for the 1920 San Francisco Lincoln Wheat Cent, doubling the earlier known count of three and reflecting ongoing research uncovering new specimens. San Francisco struck approximately 46.2 million cents in 1920, the second year of post-WWI production, and six reverse cuds indicates notable rim failure frequency for this volume. Each cud originates when the die rim — enduring the highest force concentration each press cycle — develops fatigue fractures propagating until part of the die's rim gutter is lost. On subsequent coins it appears as a raised interruption in the design rim that tracks the rim's course. Cross-referenced as CU-1C-1920S-06R, cataloged by Cuds on Coins.
