SD-10c-1983-01E Split Die

Description

Third documented crack position in what amounts to a case study in die failure, the SD-10c-1983-01E records yet another 1983 Philadelphia Roosevelt Dime die that fractured rim-to-rim along its own unique trajectory. The "E" suffix places this split at a position distinct from both the "A" and "C" orientations, continuing a pattern that makes the 1983 dime a touchstone for understanding how multiple dies within the same production run can each reach terminal failure. Split dies are the final stage before a die becomes unusable — the fracture extends entirely across the die face, and the segments move independently during striking, transferring a raised line and displacement onto every coin. The concentration of four split die positions in a single year at a single mint suggests production conditions — elevated press speeds, suboptimal die steel, or aggressive hardening — systematically shortened die life. Cataloged by Cuds on Coins, struck on Sinnock's copper-nickel clad design at 17.9mm. Identify the "E" fracture path and compare with the A and C positions to map the varied stress failure patterns.
