Prominent “Struck Through” on 2015 Gold Eagle

Struck through mint errors are caused when a piece of foreign material (often lint or grease) is struck into the surface of the coin. The foreign material then becomes dislodged but leaves behind a recessed area where the design was not struck. The name “struck through” (sometimes shortened to “struck thru”) indicates that the coin was struck through a piece of foreign material.

While it is not uncommon to come across minor struck through mint errors on American Eagle bullion coins, it is rare to see large ones. These images show a 2015 1-Ounce $50 Gold Eagle with a large area of the reverse obstructed by foreign material. An error of this size is seldom encountered and is highly desired by error collectors.

Also shown is an image of a 2015 1-Ounce $1 Silver Eagle with a large struck through around the perimeter of the obverse, most likely caused by excess grease on the coining die.
