Hi all. I have what I believe to be a 'Bold N' 1871 IHC. It has solid details but some kind of adhesive and gunk on it. What should I do? I don't want it to become damaged. What is its current value relative to possible value with conservation? Would you not feel obligated to save it? What is the general consensus here? Thanks for some input.
Acetone will remove some of the stuff on the coin but some of it looks like corrosion. The surface is already damaged.
