Struck through wire
This coin exhibits an incused thin line from a piece of wire or bristle from a wire brush that came between it and the die. A standard piece of equipment in a machine shop is a wire brush or file card that is used to clean the grooves of a file. The pressman periodically uses the brush to clean the press and the dies when they become clogged with grease and dirt. Falling bristles can find their way into the coining chamber and be struck into a coin. These often appear in a U shape and have been incorrectly called “staples.” 1878 Trade Dollar Strk Thru Possible Wire (Coin courtesy of Larry Allegrina/Photo by Ken Potter)

Struck-through
(wire bristle)
Pieces of cloth, metal fragments, wire, slivers of reeding, grease, oil, dirt,
wire bristles (from wire brushes used to clean dies, resembling staples), die covers and other objects may fall between the dies and the coin. The most collectible struck-through errors are those with the foreign object still embedded in the surface of the coin.

Ce sont des brins de la brosse qui sert a enlevé les saletés sur la surface et les cavités du coin qui sont tombé sur l'enclume (pièce de v@utour "observe" enclume) lors de l'entretien des coins et apres quelques frappes sont probablement partient ailleurs.
