But, I really like this coin, so I want to be careful. This is the way it came, haven't touch it other than a dry brush. I'm trying to get more detail from the coin and it looks like there is a brown patina beneath the green one. The color doesn't concern me, but I don't want to remove both. Just don't want to ruin this one. Thanks Report this Post to the Staff

This is recommended for treating "bronze disease." I haven't tried it myself but am preparing to. There's a fair amount of info available on the internet, for example at http://www.crescentcitycoinclub.org...0Disease.pdf, which also gives you the recipe for the solution. Apparently if done properly it can remove green encrustations without harming the underlying metal. Whatever you try, good luck to you. Report this Post to the Staff
