<p>[QUOTE=&quot;Barry Murphy, post: 7884518, member: 79368&quot;]Most ancient coins have been cleaned at one time or another, so cleaning really isn’t an issue with ancients as long as it’s well done. If the surfaces were improved the surface grade would go up. Most people unfortunately tend to over clean their coins and bright, brushed and unnatural looking cleaning will get a lower surface grade. </p><p><br /></p><p>I don’t recall this coin off hand as to why it was a 3 surface. If there are underlying scratches or surface porosity, cleaning won’t improve the grade because those issues will still be present, in fact cleaning might lower the grade if those issues became more obvious and distracting. </p><p><br /></p><p>It doesn’t matter if NCS conserves the coin or you do. We just grade the coin as it’s presented to us. If we had thought that having NCS conserve the coin would have improved the grade, we would have recommended it. </p><p><br /></p><p>Barry Murphy[/QUOTE]</p><p><br /></p>
