<p>[QUOTE=&quot;cpm9ball, post: 1495124, member: 24633&quot;]I&#039;m not quite sure that I understand what you are asking. Do you mean, &quot;Can it happen that the act of conservation may cause a coin to receive a &#039;Details&#039; grade?&quot; No!</p><p><br /></p><p>Sometimes, the conservation can uncover a problem that was hidden by the surface contaminants that were removed. In cases like this, NCS has no way of knowing about the underlying problem, and naturally, NGC would have no alternative but to assign a Details grade. However, the mere act of conservation cannot be responsible for a Details grade.</p><p><br /></p><p>One more thing! Some people are under the false impression that conservation will restore a coin or medal to its original state. This isn&#039;t always the case. Sure, they can do their best, but they are not miracle workers. A good example of this is the 1978 Silver Valley Forge Bicentennial medal below. When I bought this in a bulk lot, the original owner had stored it in his garage (IN SOUTH FLORIDA!) and the heat and humidity had taken its toll. If I had merely tried to submit it &quot;as is&quot; for grading, it would have received a Details grade for environmental damage, but after conservation, it graded PF66 UCAM. Yes, you can still see the effects of the contaminants, but it is far better than it was.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
