<p>[QUOTE="GDJMSP, post: 8171804, member: 112"]The single spot by the eye - that's verdigris.

That said, there are other things, methods, that many have done over the years to remove verdigris, but pretty all require mechanical efforts - meaning you have to physically scrape/scratch it off. Now [USER=24314]@Insider[/USER] has a method that seems to work pretty well but he knows more about and has more experience with the proper cleaning of coins than just about anybody - so that doesn't mean that just anybody else is gonna be able to do what he does.</p><p><br /></p><p>There's something else that needs to be said about verdigris, two somethings actually.

Think of it as being "rust" on copper, just as rust is on iron or steel. The thing that is causing the corrosion is copper interacting with the air, and the moisture in the air - it's the very same mechanism that causes rust to form on iron or steel as it corrodes. </p><p><br /></p><p>The point here is that if you want to stop verdigris, there's no need to remove it, as I said the damage has already been done so removing it isn't really going to do anything except maybe improve the "looks" of the coin. But removing it also exposes the damage that has been done to the eye. So you trade one bad thing for another bad thing by removing it. To stop additional verdigris from forming what you have to do is control the air and the moisture in it from getting to the coin. And you do that with proper storage methods. Use proper storage methods and no more verdigris will form on the coin.</p><p><br /></p><p>So what are proper storage methods ? Well they've been written about and explained on this forum more times that I can even count. So simply do a search for them and read what you find. But here's the thing about proper storage methods - it seems a whole lot of people don't want to bother with them. They consider them to be too much trouble or too expensive. In other words they like doing things just the way they've always done them. But proper storage methods exist and it's not really difficult to utilize them, but for them to work, that's what ya gotta do - utilize them. And if you don't, then you, or rather your coins, very well may suffer the consequences.[/QUOTE]</p><p><br /></p>
