SD-10c-1983P-01 Split Die

Description

One of the most remarkable die failure progressions in the Roosevelt Dime series, SD-10c-1983P-01 records a split die cap across eight sequential stages designated A through H. A split die occurs when a working die fractures along an internal plane, physically separating into sections — and here the separated die became a die cap, adhering to the die face and intervening between die and subsequent planchets. Each stage from A through H captures progressive deterioration as the split die cap degraded, producing increasingly distorted impressions on every planchet fed through the press. Cataloged by Cuds on Coins on a 1983-P Roosevelt Dime struck at Philadelphia in copper-nickel clad, this eight-stage progression offers an unusually complete record of catastrophic die failure in real time. The sequence lets collectors trace how each successive strike compounded the damage, with early stages showing relatively coherent impressions and later stages displaying severe distortion. Few die failure varieties in any denomination offer this depth of progressive documentation, making the complete A-through-H set a prized study collection for error specialists.
