PART VI. Striking Errors:

“Struck-Through” Errors:

Struck Through Miscellaneous Foreign Matter:

Struck through wire

Definition: Metal wires are sometimes struck into planchets, leaving thin incuse impressions that can be straight, kinked, curved, worm-like, or sinuous.

This 1988(P) Lincoln cent shows a thin impression from a wire that extends from the L of LIBERTY down towards Lincoln’s shoulder. The width and depth of the impression makes it unlikely that this was a wire from a cleaning brush.  It may be a filament from a piece of steel wool.
