<p>[QUOTE=&quot;Randy Abercrombie, post: 5399826, member: 92655&quot;]Toning, spotting and tarnish absolutely can happen in a sealed TPG slab. It happened to me on a very expensive coin. While they are sonically sealed, the slabs are not necessarily air tight. In my case, the coin was in a gun safe and the airborne gun cleaning chemicals turned my coin almost entirely black. Lesson learned.... I have also seen coins displayed on shelves that toned due to the daily sunlight coming through the window and slowly turning the displayed coin. So the lesson in all this is the slab is superb at protecting the coin from physical damage. However if your desire is to keep the coin in its pristine state, you need to store it carefully. I place my coins in ziplock type bags to mitigate moisture for example. Good luck and enjoy your purchase.[/QUOTE]</p><p><br /></p>
