<p>[QUOTE=&quot;desertgem, post: 3961760, member: 15199&quot;]I suspect any waxy substance would make almost any circulated coin look better, but the question should be ; what happens when these saturated hydrocarbons (lipids) start to break down over time ?. You can get all sorts of short chain hydrocarbon compounds produced depending on environmental factors. I am sure it depends a great deal on the company producing the product. I can&#039;t imagine the museums that use this on coins and metal haven&#039;t produced reports or at least guidance for replacement. It is similar to paraffin except it has smaller wax crystals and I am not quite sure why that is important for coin storage as the chemistry is quite similar. IMO, Jim[/QUOTE]</p><p><br /></p>
