<p>[QUOTE=&quot;Markus1959, post: 2262831, member: 73174&quot;]I worked in a foundry and you would be surprised at what we would push into the drag mold then have the cope mold over it - made some pretty good copies of coins and medals but yes - ALWAYS a porous surface no matter how tight the sand was tightened up by binders. Stamped coin surfaces are nice and &quot;smooth?&quot; from the pressure on the planchets/blanks as the metal flows across the dies to form the highlights&nbsp; (raised sections of the coin/medal)!![/QUOTE]</p><p><br /></p>
