Consider the possibility that it isn't PVC.
If that's the case acetone might not affect it.
It could be verdigris spot from the copper that the coin is alloyed with.

OK, I'm starting the second acetone dip right now. I'll try to leave it in as long as I can, as New England weather can be quite volatile this time of year, and I don't want any flammable acetone in the house unattended. Hopefully this one will remove the PVC.

Excellent thread, thank you! That's a good reference. Do you still have that coin?

It's been approximately 24 hours with no change. SsuperDdave, you suggested 5 days, and I trust your numismatic expertise! Back in the acetone it is then.  Besides, even if the green spot doesn't go away, I can always sell the coin. I only paid $65 for it, and the Red Book has this date at $95 in MS-64. Although I doubt that I could get even close to $95 for it since a) the Red Book values are usually high b) it wasn't that strong of a 64 anyway c) it's not in the slab anymore d) it has minor PVC issues So hypothetically, if I decide to sell the coin, I'll most likely get the greysheet bid price for this date in $63. Who knows? I might break even maybe! And even if I don't I won't lose too much anyway. I'll think it over... |

Just took the coin out after 5 days in acetone. The spot looks duller, more of a grayish-green than a bluish-green. It may have shrunk a bit too, but it's definitely still there. I don't know, it sure is hard to tell with only a 10X loupe. I need a microscope or something. I'm thinking it over, but I'm leaning towards selling the coin. Besides, I might be going to the Westford coin show on the 25th, so if I sell the coin and pool together some cash I already have, I might be able to afford something even nicer! Like a toned Morgan dollar certified in MS-65...  Thank you all for your help and advice! |

Did I ever mention you have to work the spot with a toothpick? My bad.  |

I tried a wet q-tip on it, just the *lighest* dabbing on it. I'll give the toothpick method a shot, even if it slightly terrifies me.  |

For a silver coin with non-PL surfaces, I'm not worried about a toothpick (use a thorn if you have roses). Work from the side of the spot at a low angle, "pushing" towards the center of the spot rather than "scratching" side to side.
