Countermarked: The impression left by a countermark punch. A tool that is used to punch into a coin subsequent to the original striking an additional mark or symbol that had meaning in the contemporary context of the coin - for example to mark a specific payment or to revalue a coin). Objects from early modern collections sometimes bear countermarks as a sign of ownership.
