CU-10c-2011D-01 Cud

Description

Cataloged by Cuds on Coins on October 1, 2013, CU-10c-2011D-01 stands as the only documented cud on the 2011 Denver Roosevelt dime — a major rim die break that left a featureless raised area on the struck coin where the fractured die could no longer impress design detail. No cross-references to other error catalogs exist for this variety. The 2011-D dime was part of the ongoing clad Roosevelt dime production that Denver has maintained continuously since 1968 (excluding the mintmark-free period of 1965-1967), and this date saw a mintage of approximately 748 million pieces. Dime cuds present a particular visual character distinct from cuds on larger denominations: the smaller 17.91mm planchet means that even a modest die rim fragment, when broken away, creates a cud that covers a proportionally larger arc of the coin's circumference compared to the same-sized break on a quarter or half dollar. This proportional scaling makes dime cuds visually dramatic relative to the coin's size, even when the absolute dimensions of the break are modest. Denver Mint die failures that produce cuds typically occur when the hardened steel working die develops fatigue cracks at the rim — the highest-stress zone during striking — and these cracks propagate until a wedge-shaped or irregular fragment separates entirely. Quality control procedures should catch severely broken dies during routine inspections, meaning cud coins often represent brief production windows between the die's fracture and its replacement, contributing to their relative scarcity.
