<p>[QUOTE=&quot;Insider, post: 4420912, member: 24314&quot;]IMO, all the above coins would straight grade if sent in.&nbsp; </p><p>These spots are part of the coin&#039;s surface and are technically not &quot;problems.&quot;&nbsp; Generally, copper spots will reduce a grade a little.&nbsp; For example, if a coin just makes MS-64 they may drop it to a high MS-63.&nbsp; Copper spots are rarely tolerated on coins over 65.&nbsp; If they are on these coins, it probably developed after the coin was slabbed. </p><p><br /></p><p>The idea for NCS was planted when I removed copper spots from a $10 Indian and it was graded higher.&nbsp; A short time later I did another conservation.&nbsp; That got the ball rolling and NCS went from a Janitor&#039;s sink room to a state of the art lab.</p><p><br /></p><p>&quot;Spot Removals&quot; are a different thing.&nbsp; They are scratch damage to the surface.&nbsp; They can also be seen as abrasive spots where the top layer of metal is removed.&nbsp; This is more commonly seen on copper coins.[/QUOTE]</p><p><br /></p>
