In modern currency presses, it is imperative to adjust the minimum distance between the two dies to prevent collisions, even in the absence of a planchet. Nonetheless, incorrect adjustments or malfunctions can reduce the minimum distance to zero, which may result in die collisions if a planchet is not fed into the ferrule at the time of minting. This collision will imprint both surfaces with images of the opposite die, resulting in coins with additional traces in incuse and inverted positions on both sides.
