[QUOTE="gxseries, post: 101604, member: 4373"]Verdigris is like a two-edge sword if you wouldn't like to believe me.

The trick I guess when cleaning such coins is to find out what areas would show up horrible pitting and to take special note of and to preserve it next. I'm sure Mike (mmarotta) will be able to tell very speificially on such cleaning / preservation process. edit: sorry, I wasn't paying attention to my grammer (lol)[/QUOTE]
