SD-1c-1972D-01 Split Die

Description

Representing the terminal stage of die failure, SD-1c-1972D-01 documents a 1972-D Lincoln Memorial cent struck through a late-stage split capped die — a remarkable compound error where the die first split into major sections, then one section became capped (adhering to the hammer die face), and subsequent coins were struck through the capped fragment, receiving an indirect impression rather than a direct strike from the intact die. The Cuds on Coins attribution team cataloged this extraordinary variety with the note confirming the struck-through-cap mechanism. Split dies represent catastrophic structural failure: unlike a bisecting crack where both halves remain functional, a split die has separated into pieces that can no longer maintain proper alignment. When a split die section caps (sticks to the hammer die), it interposes itself between the die and the planchet, causing subsequent strikes to receive a progressively degraded impression — each additional coin struck through the cap further distorts the capped fragment, producing increasingly mushy, spread, or ghost-like images. The coin documented as SD-1c-1972D-01 was struck after this capping occurred, meaning its design was not imparted directly by the die face but filtered through the intermediary of the capped die fragment. This produces a distinctive softened, expanded appearance fundamentally different from a simple weak strike. No external cross-references have been established. The sequence of events this coin records — die splitting, fragment capping, continued striking — represents multiple failures compounding in rapid succession, likely spanning only seconds of real-time production before the press was stopped or the cap dislodged.
