For those of you who contend that green corrosion/verdigris will continue unckecked if the coin isn't stripped and retoned, please explain to me...
You can always think of that spot like this -- it likely saved you a good bit of money, and it is on the reverse, after all. :) That's a nice...
High grade clad business strikes from the early 80's.
Nice color on those pics.
That's a great piece of copper, Kanga. Great luster and color -- I'd be proud to own it!
That's a Good coin all day to the TPGs. Quite frankly, it wouldn't surprise me in the least to see it in a G 6 holder, or even (if the reverse...

It was the nitric acid that dissolved the coin, not the air or water, per-se. It is my understanding that there are sulfates in the air...
As I understand things, neither -- it is the addition of sulfur (or chlorine) to the humidity that really causes the damage (see prior post for...
Thanks for sending the link, that's a wonderful site! A few points... o The site is addressing how to conserve copper that's been buried in the...
