<p>[QUOTE=&quot;desertgem, post: 681087, member: 15199&quot;]Thad, of course , I would want to see such a book also. After reading the selection, you provided, I wonder if you should include a section on ancient coins, especially the mineralized compounds you mention that seem to be their bane, although they can certainly have the same problems as lincolns. Not on removal, just as part of the chemical formation and preservation. I have seen a few coins recently here that come very close to mineralization and normal conservation techiniques just won&#039;t work as you say. Nicely written by the way !</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
