SD-10c-1972D-02 Split Die

Description

When a working die cracks completely from rim to rim, the result is a split die — and the SD-10c-1972D-02 preserves exactly this kind of catastrophic failure on a 1972 Denver Roosevelt Dime. Unlike a simple die crack that runs partway across the surface, a split die fracture divides the die into two or more sections that shift under repeated striking pressure, producing a raised line and displacement on every coin struck. The small diameter and thin dies used for dime production make Roosevelt Dimes particularly susceptible to this terminal failure, and the high-volume Denver production runs of the early 1970s pushed dies through extended service that increased the likelihood of complete fracture. Cataloged by Cuds on Coins as the second split die on 1972-D dimes (SD-10c for split die on a 10-cent denomination). Sinnock's Roosevelt Dime, struck on copper-nickel clad at 17.9mm, has been in continuous production since 1946. Look for the rim-to-rim raised line and adjacent displacement.
