I've had this for several years and it seems to have gotten darker . Should I let it go ? I call it the "Black Ring of Death " . Don't mention Acetone . I can't be near it .
Color really does not matter on bullion coins like that. If you like it shiny, get some coin dip. Acetone will not remove toning.
Well , not happy with the black ring of death, I tool care of the problem. Can you tell ? At least it's not Black but rather a pinkish hue .
