A coin exhibiting an error caused by the failure of the coin press to release the previous coin from the die before striking it. The design from the first coin is imprinted, sunken in reverse, on the second coin. Brokage coins appear to have the same design on both sides with one side showing a reverse or mirror strike which, because the previous coin acts as the die, does not usually have the same quality of detail.
a Mint error , an early capped die impression where a sharp incuse d image has been left on the next coin fed into the coining chamber
an early form of mint error which results from the use of a previously-struck coin as a die
An indented strike due to another previously-struck coin adhering to the hammer die, creating an incuse (depressed) spread image on the coin. 215
A mis-struck coin showing two heads (or two tails), caused by failure to remove the previously struck coin from the dies before striking. A second coin receives an indented impression of the head of the first coin.
A mirror image of the design from one side of a coin impressed on the opposite side - occasionally, a newly struck coin "sticks" to a die, causing the next coin struck to have a First Strike Mirror Brockage of the coin stuck to the die; by the second strike the mirror is distorted, and later strikes are termed Struck Through A Capped Die
a mis-struck coin resulting from the failure of mint personnel to remove a coin which had lodged in the reverse, or upper die, after having been minted. The new coin would receive two obverse impressions, one from the obverse die and the other from the lodged coin. The impression from the lodged coin would be incuse (recessed). Brockage coins with two reverses are much rarer due to the lodged coin being visible in the lower die, and the new coin blank having to be placed upon it.
A mis-strike on a coin; generally one showing the normal design on one side and an incuse mirror image of this design on the other side of the coin.
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.
