Lathing the coin edge is a procedure by turning the coins around and around against a sharp tool or graver, the redundant fragments of the coins would fall apart and finally the coin’s edge becomes smooth. This process would generally be used for the metal challenge coins, military coins, souvenir or commemorative coins which require high quality, 100% round or required the ribbed edge.
