I have the chance to pick up a nice copper coin but it has black spots on it. In the fields, around and on the raised details, etc. I don’t buy coins like this so can these black spots be removed? Is conservation by a professional recommended? Thanks for your help in advance.
I believe conservation can be achieved but depending upon the coin, the cost of such might be prohibitive.......
What coin is it? Black spots can obviously lower the grade of a coin but I've seen straight-graded copper with these spots, albeit they're quite light while still noticeable. One more question: do you have pictures of the coin?
No photos as it’s not mine. It’s a solid mid grade coin on the scale of 70. The black spots don’t lower the grade as it’s a details grade with them.
Depending on the coin. Rarity and condition after the conservation VS price...Can you buy the same coin without the issue for the same $$? Keeping in mind, I'm under the impression that COPPER once it has an issue, it's always going to have said issue and years down the road could show up again.
