[QUOTE="GDJMSP, post: 4774559, member: 112"]The part I underlined in your comment isn't "exactly" true. Yes, it is true that IF stored properly, then then there will be no more verdigris forming on the coin. But, IF it is not stored properly then there probably will be more verdigris forming on the coin. The key to preventing it is proper storage. Verdigris, the green stuff, forming on a coin is what happens when the copper in that coin corrodes. And yes, even most silver and gold coins have some copper in them, that's why verdigris can form on them. However, before corrosion and the formation of verdigris can occur, it is necessary for moisture to be present. And when I say moisture I'm referring to moisture in the air - humidity. So, cut off the moisture and reduce the air flow by utilizing proper storage, and there will be no more verdigris forming on the coin. But if proper storage is NOT utilized, there is a high probability there will be more verdigris. And Paul, [USER=103058]@PaulTudor[/USER] , if you want to know what proper storage methods are, just do a search using those 2 words as your key words, and my user name in the "posted by" line of the search. You'll find what ya need to know.[/QUOTE]
