<p>[QUOTE=&quot;GDJMSP, post: 1588672, member: 112&quot;]Precisely the the point. But to be more accurate, some use the incorrect terminology. And yes, that includes Margolis &amp; Weinberg. The marks from a dies clash are not &quot;polished away&quot;. To say they are ground away or sanded away would be far more accurate.</p><p><br /></p><p>Dies are polished with a large, spinning zinc disk, on a machine. The face of the zinc disk is covered with varying grits of diamond dust to polish the die, courser grits are used at first, followed by progressively finer grits, until the desired result is achieved. This method goes back to the 1800&#039;s, and is still in use today.</p><p><br /></p><p>The criss-crossing marks seen on coins are, and should correctly be called die scratches - not die polish lines.[/QUOTE]</p><p><br /></p>
