Description
A reverse cud documented for the 2006 Philadelphia Colorado State Quarter. Norman E. Nemeth's Colorado reverse, depicting a Rocky Mountain landscape with "Colorful Colorado" banner, features significant relief transitions between mountain peaks, valleys, and the flat banner area that create stress concentrations near the die rim. Philadelphia struck over 274 million Colorado quarters in 2006, subjecting each reverse die to enormous cumulative striking forces throughout its service life. Cataloged by Cuds on Coins with no additional cross-references established from other attribution organizations. The Colorado State Quarter's cud-rich history makes it a prime target for die break specialists assembling comprehensive State Quarter error collections, alongside other famously cud-prone issues like the 2004 Wisconsin and 2005 Kansas quarters.
