Brockage

A brockage is an error coin. One side (most of the times the obverse) is normal, but the other side instead of the reverse displays the obverse again, incuse or in negative.

In just a few words, a coin is produced by inserting a piece of metal, called blank (1) between two dies (2a,b). One of the dies is fixed (in a type of anvil setup), the other is mobile, held by a worker with tongues. With his other hand the worker (or another worker) applies a hammer blow to the mobile die and the engravings of the dies are transferred in positive to the blank resulting in a coin (3). Another blank is positioned and struck, and so on.
