Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In minting, coining is the process of manufacturing coins using a kind of stamping which is now generically known in metalworking as "coining". A coin die is one of the two metallic pieces that are used to strike one side of a coin. A die contains an inverse version of the image to be struck on the coin. To imagine what the incuse version looks like, press a coin into clay or wax and look at the resulting inverted image. Modern dies made out of hardened steel are capable of producing many hundreds of thousands of coins before they are retired and defaced.
