Just visualize a flat piece of metal being pushed through two rolling pins that are going to be exerting a lot of pressure on that piece of metal. On these rolling pins are the dies used in the minting of the coinage. There were a few different types of roller die mint presses. One type used rollers that had dies all the way around it, and another type of roller press used a single obverse and reverse die on the rollers. Take a look at the pics of the rollers and dies used.</b></p><p><b><br /></b></p><p><b>pic 1) this is a roller die with dies all the way around the rollers.</b></p><p><b>pic2) this is a milling press that would flatten out the strip of silver before be put into the minting press</b></p><p><b><br /></b></p><p><b>pic 3) this is a different type of roller die in which only one obverse die and one reverse die is used on the roller.</b></p><p><b>pic 4) this is the minting press which used a single obv. and a single rev. die.</b></p><p><b><br /></b></p><p><b>Pic 5) this die shows how much of a bend a coin could have.</b></p><p><b>Pic 6) click to make this pic bigger.
