PVC that's eaten into the surface of the coin often results in a black spot...

is there any way to remove the or recolor this black spot so it isn't so ugly?

I've never actually seen a black spot from PVC damage, though this isn't to say that it cannot happen, but once the underlying metal has been damaged then you would need more than just color to hide it if the spot is removed.

I know. Even when the spot is removed the damage is still there. But I'd rather have a silvery spot than a black spot.

If it's a silver coin, a black spot probably is carbon, not PVC, it's green and slimy. PVC will soak off with acetone, a carbon spot won't.

The spot was PVC. I was able to soak it off with acetone, but this black spot was underneat. Looking at it under a scope, it's not a carbon spot, it's residue of the acid-eaten metal.

I would love to see a picture then, because I'm like Tom, I've never seen black from PVC. All I've ever seen is what looks like a bad milk spot where the "skin" is gone.
