1975 Typical Die Clash TDC-1C-1975-01

Description

Cataloged as TDC-1C-1975-01 by MadDieClashes, this typical die clash variety was struck at the Philadelphia Mint without a mint mark as part of the 1975 Lincoln Memorial cent production. A typical die clash occurs when the obverse and reverse dies come together without a planchet between them, and each die impresses its design into the face of the opposing die. On subsequent strikes, the affected dies transfer faint, incuse ghost images of the opposing design onto finished coins — most commonly visible as traces of Lincoln's portrait on the reverse or fragments of the Memorial building on the obverse. Die clashes were a recurring phenomenon at all U.S. Mint facilities during the high-speed production era of the 1970s, when automated press lines operating at hundreds of strikes per minute occasionally misfed or failed to eject a coin, allowing the dies to meet without an intervening planchet. TDC-1C-1975-01 is the first documented die clash for the 1975 Philadelphia date, and the Philadelphia Mint's production of cents without a mint mark during this year was enormous, creating ample statistical opportunity for clashing events across the facility's multiple press lines. Collectors should examine both sides of candidate specimens under magnification, looking for the telltale transferred design elements that distinguish a die clash from normal die wear.
