Description
CU-25c-2006P-09R(CO) is a reverse cud recorded for the 2006 Philadelphia Mint Colorado State Quarter. The collective record documents instances where reverse dies fractured at the rim — each producing the characteristic raised featureless mass where metal filled the cavity left by the separated die fragment. Norman E. Nemeth's Longs Peak design, with its detailed mountain topography and evergreen foreground, required dies to maintain sharp relief across a complex composition. Colorado was admitted to the Union in 1876, and its quarter was one of five 2006 releases. The cumulative evidence suggests that Colorado quarter production pushed dies to their mechanical limits with notable regularity.
