PART VI. Striking Errors:

Struck Through Errors: 

Struck Through Hardware

Definition: When it comes to foreign objects finding their way into a coinage press, almost anything goes. Bolts, screws, washers, and machine parts such as a feeder finger are occasional targets. Any coin trapped between a die and any of these objects is severely traumatized.

This off-center 1982 cent was struck through a threaded bolt on the left side. The left side of the coin was pinched off and lost as a result of the impact.
