The coin error known as “Struck Through Coin – Brockage” occurs when a newly minted coin remains attached to the upper or lower die during the striking phase. This results in another planchet being introduced into the beating chamber, which is then struck together with the previously trapped coin. In certain circumstances, the trapped coin assumes the role of the die and imprints its image in incuse and in an inverted position on one side of the coin. The opposite side of the coin then receives the imprint in relief and in a regular position.
