<p>[QUOTE=&quot;Marshall, post: 962449, member: 21705&quot;]I think it is worth NCS conservation since you haven&#039;t got the experience in conservation. If you choose to take the time to learn on less valuable copper, it may change the cost benefit equation. Now you have to understand that the coin is already damaged by the verdigris and removing it will still leave evidence of that damage, but it should prevent continued destruction of the original copper which appears to currently be active. </p><p><br /></p><p>You will probably get either an Environmental Damage or Cleaned notation but that&#039;s because it is or would be. I don&#039;t think anything other than very light verdigris can be removed and leave insufficient damage showing to get a grade without some notation.[/QUOTE]</p><p><br /></p>
