A brockage is an early form of mint error which results from the use of a previously-struck coin as a die. We suppose that this normally resulted from a freshly-struck piece adhering to the punch die as a result of surface tension, or simply the adhesiveness of heated metal; a virgin flan was then inserted on the anvil die and struck with the punch, so that the obverse previously produced by that anvil die appears in incuse as the reverse of the new coin. Eventually the first coin drops from the die and coining proceeds as usual; the flawed pieces escape detection and find their way into circulation.
Full brockage Errors are rare and the most desirable form of the error.
