Broadstrike
In addition to the obverse die (anvil) and the reverse die (hammer), striking a coin requires a third die called collar. This collar makes it possible to obtain a precise diameter for each coin of the same denomination and it contains the overflow of the metal when the blank is struck.
Sometimes a blank does not fall completely into the striking chamber. This blank may partially rests on the collar (off centered). When this happens, it is partially struck. The collar, by the pressure of the strike, will follow the downward movement and then rise again without the coin being folded up, then it will be ejected normally.
