Coining (mint)

In minting, coining or coinage is the process of manufacturing coins using a kind of stamping, the process used in both hammered coinage and milled coinage.[lower-alpha 1] This "stamping" process is different from the method used in cast coinage.

A coin die is one of the two metallic pieces that are used to strike a coin, one per each side of the coin. A die contains an inverse version of the image to be struck on the coin. Striking a coin refers to pressing an image into the blank metal disc, or planchet, and is a term descended from the days when the dies were struck with hammers to deform the metal into the image of the dies.

Modern dies made out of hardened steel are capable of producing many hundreds of thousands of coins before they are retired and defaced.
