Coin-stamping tools are composed of two components: dies and punches. Dies are the metal pieces that have a raised design on one side and a recessed design on the other. They are used to stamp coins with the raised design. Punches are the metal pieces that have a recessed design on one side and a raised design on the other. They are used to create the recessed design on coins. Together, dies and punches form the coin-stamping tools used to create coins.
