I have some toned coins that the stage of toning, is not the attractive variety. An example would be darkish brown on edges, almost a nicotine type color. I find it detracts from the coin. I'm wondering if there's a chance for it to either spread or change to a nicer shade? It's in a 1995 birds of Canada silver fifty cent piece and a 1984 silver dollar. Sorry no pics, I suck at uploading.
I'm also curious if this will affect the selling price negatively? The toning is on outer edge, only 1 side and half way around. All I put is welcome. Rox
