Instead of using additional heat from the laser to create a bigger hole, the melt and blow laser cutting tools use a blast of compressed gas to push the melted material out of the cut after the material has reached its boiling point.</p><p><br /></p><p>Your coin was most likely subjected to one of these fancy laser cutters.&nbsp; Your coin looks as if the metal is flowing from the center to the outside.&nbsp; Machine shop follies.[/QUOTE]</p><p><br /></p>
