I have 2 coins, from different auctions, but most likely from the same source (I have seen many coins with the same issue in the same auctions) I got this coin because I liked the reverse, but as you can see, on the obverse the damage is quite extensive. The previous coin I got has the same problem (and also Julia Maesa, apparently she hates PVC). I soaked the old one in acetone - but not pure acetone as I don't have it, I need to buy some soon - but the effect was unnoticeable. I dipped it with a Q-tip and either I'm paranoid or some portions started to shine, unnaturally, so I just left it alone. Without the damage, this coin, and the other one, would have been quite attractive coins ... Do you think I should try something on this one or not? I am not bothered by the green spots and not very bothered about the damage itself, my only concern is if the coin will continue degrading.
