<p>[QUOTE=&quot;Just Carl, post: 515489, member: 4552&quot;]Absolutely not true. If that coin has just started to turn green, it is more than likely just a coating or patina and should, or might, come right off with Acetone or ever just distilled water. If not and you don&#039;t really care and the Acetone does not work, try distilled water and baking soda solution. Soak in that and gently, very gently rub with that solution and rinse with distilled water. </p><p>First start with soaking in the distilled water for a few days. Then if nothing, try the Acetone. Last resort is the water/baking soda. </p><p>In way to many instances people blurt out Verdigris without knowing what it is on your coin. Or they say PVC and again have no idea of what it may be. </p><p>Copper piping outdoors almost always turns green. In some areas of the country this happens faster than in other places. Coins in wood boxes that have absorbed moisture also give it off. </p><p>Copper, Cu, usually combines with Oxygen, O to form Cu2O. this in turn combines with moisture, H OH, known as hydrogen Hydroxide or water, and Carbon Dioxide, CO2 to form [CuCO3-Cu(OH)2] or Copper Carbonate a dull greenish layer or patina. </p><p>That sounds like your coin.[/QUOTE]</p><p><br /></p>
