<p>[QUOTE=&quot;John Burgess, post: 4901240, member: 105098&quot;]one more thing, it is a copper coin,&nbsp; the greening, is verdigris. It&#039;s copper acetate and copper carbonate and itself is oxidization corrosion as well as a contaminant that will continue to corrode. Any way you do it, it should be removed to save the coin from getting worse really, especially if it&#039;s special to you, then the sale value of it really isn&#039;t that important to consider as far as the cost of conservation goes so it can be around to pass to another 2 generations. </p><p><br /></p><p>you can read some info from NGC conservation on this link</p><p><a href="https://www.ngccoin.com/ncs-conservation/" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.ngccoin.com/ncs-conservation/" rel="nofollow">https://www.ngccoin.com/ncs-conservation/</a></p><p><br /></p><p>read it and look around there to get a better idea of the service.</p><p><br /></p><p>important to note, that they say &quot;may be be numerically graded or details graded&quot;</p><p>and then it goes into hidden damage, corrosion, ect.</p><p>&nbsp;toning that covers hairlines from cleaning that once removed makes the cleaning of the coin apparent. things that conservation may uncover that don&#039;t currently look as bad can look worse once uncovered.</p><p><br /></p><p>as far as loss, the mail would lose it if anyone really. insure it for it fair market value, the shipping company won&#039;t pay out more than that anyways, usually what it would cost on average to replace it is the maximum. </p><p><br /></p><p>as far as damage, no, nothing they would do would damage your coin, however, them conserving it may uncover damage that was hidden or less noticeable due to toning.</p><p><br /></p><p>if it won&#039;t benefit the coin to do it, they will not do it. </p><p>it will not improve the coin or the grade of it, just improve the eye appeal and stabilize the surface again by removing the affecting contaminants.</p><p>if damage is done, it can&#039;t be undone.</p><p><br /></p><p>&nbsp;it can be conserved and get a details grade for &quot;environmental damage&quot;, this is a possibility.[/QUOTE]</p><p><br /></p>
