<p>[QUOTE=&quot;Barney McRae, post: 25294785, member: 150594&quot;]I found this thread looking for what causes toning and what accelerates it. I purchased two sleeves of 2000 Silver Eagles back then from a TV coin show. They are 20 to a sleeve, soft plastic US mint tubes. I take them out maybe once every 5 years to look at them. About 10 years ago I noticed 2 or 3 had started to get some toning. Maybe they were enders, I don&#039;t know. But the tubes are sealed airtight, it requires some effort to get the top off. But that&#039;s not why I came here, I have a question. If someone 20-40 years ago&nbsp; lightly abrasively rubbed a coin, will toning form a new patina and fill those tiny hairline gaps? (I am talking about coins in general, not those Eagles). Or will it just mask and hide them at 30X magnification? I don&#039;t think TPGs use higher magnification for grading, just attribution?[/QUOTE]</p><p><br /></p>
