SHD-10c-2007P-06 Shattered Die

Description

Six documented shattered dies from one date-mint is unusually high, and SHD-10c-2007P-06 adds to evidence that 2007 Philadelphia dime production faced systemic die quality issues. A shattered die is the end stage of progressive die failure — what begins as individual cracks gradually multiplies and interconnects until the die face is fractured into a network of fragments held together by the die housing and collar pressure. Coins struck from these terminally failed dies display raised lines across their entire surface, creating a distinctive crackle-pattern that experienced collectors can identify at a glance. The concentration of six shattered die varieties in a single year at one facility raises questions about die steel batch quality, heat-treatment parameters, or production pressures that kept dies in service beyond prudent limits. Philadelphia Mint production on copper-nickel clad planchets. Roosevelt Dime design by John R. Sinnock. Each of the six shattered dies produced a unique crack pattern, making them individually attributable. Cataloged and verified by Cuds on Coins.
