BROCKAGE: A mint error caused by a struck coin not releasing properly from the die. As a result, the sticking coin actually becomes the new surface of the die that it adhers to. When a fresh blank is placed for striking, the facing image of the previously struck coin transfers its image into the fresh blank in Incuse form. The result is a cameo image on one side of the newly struck coin and the identical image incuse and reversed on its opposite side. Generally, it is the image from the anvil die that appears as a brockage. This is because a coin sticking to the punch die would not be as noticeable by mint workers as one sticking to the anvil die. A coin sticking to the anvil die would normally be brushed aside by the placement of the succeeding fresh blank. It is possible, however, for a fresh blank to be placed on top of previously struck coin that has lodged itself in the anvil die. This would result in a brockage of the punch die image. Brockages may be found in nearly all forms of struck coinage, but larger and heavier blanks are less susceptible to brockage than smaller and lighter coins. The illustration here is of a Roman Republican denarius brockage of RSC Valeria 11
dated about 108-107 BC.
