What was this coin colored/toned with?
I don't usually buy middle date coins, but I found a really nice 1820 N-5 (I think) in what I'd guess by EAC standards is VF30, if not better. Under a 10X hand lens it apparent that it's been recolored (a very good job too) with some compound that appears the color of cordovan or dark brown shoe polish.......that's the color of it, I'm sure it's not shoe polish! Just curious if anyone knows what it might be colored with. Should I try to remove it or just let it be? It's a pretty decent looking coin.....thanks......clorox
