<p>[QUOTE=&quot;Conder101, post: 3534633, member: 66&quot;]No, the spark erosion process is used to make the dies.&nbsp; You use a coin and a flat faced die blank.&nbsp; Mount the coin parallel to the die blank and apply a high voltage pulsating DC across them.&nbsp; A spark will be created from the high point of the coin to the die blank and with each pulse the spark will erode a tiny pit in the die face (the size of the pit probably being a function of the voltage, the higher the voltage the larger the pit and the faster the process but the cruder the final die with less fine detail.).&nbsp; As the process continues the cumulative pits will erode the die face till it parallels the contours of the coin.&nbsp; The die can then be hardened and polished&nbsp; and used to strike fake coins.[/QUOTE]</p><p><br /></p>
