From Wikipedia, the free encyclopedia
In Coin collecting, brockage refers to a type of error coin in which a side of the coin has both the normal image and a mirror image of the opposite side impressed on it. This is caused by an already minted coin sticking to a die and impressing onto another coin. Brockage is relatively rare and, in good condition, coins showing definite brockage can sell for large amounts of money. One can distinguish between obverse and reverse brockages. Obverse brockages occur when the previously struck coin was not ejected and gets stuck to the lower die, and reverse brockages when the previously struck coin remains stuck to the upper die.
