One of the Morgan dollar coins I received from my grandfather has a serious green issue. What's your diagnosis? And is it treatable? Or is it doomed?   Thanks for your input, -Lance-

Looks like PVC plasticizer damage. Might be able to treat it with acetone.

I heartily concur with the captain's diagnosis. The PVC likely migrated from an old holder. You can apply the acetone (hardware store, NOT nail polish remover) with one end of a Q-tip, massaging gently. Use the dry end to lift the residue. You'll likely need to repeat the process, doing both sides and the rim. You can dry it with a soft cloth, afterwards. Avoid putting the coin in an old flip that has PVC. As this is a common, lower grade date, there's no downside with this form of cleaning; that is, in this case, more appropriately defined as conservation. Show us an after pic, please.

What's wrong with your coin? It doesn't belong to me!
(kidding...kinda). These guys have excellent advice - please follow it and then enjoy her.

I set aside a small amount of acetone last night from a can I have a had for a while.  If it passes the evaporation test, I'll get to work. Otherwise, it's off to the hardware store for me. CoinsKelly, definitely going to enjoy her.  That's why I am worried about her condition -- would hate for any further damage to occur.

Finally got a chance to some conservation work last night.
The acetone worked like a charm. Dipping a Q-Tip in the acetone and gently blotting in a rocking motion lifted the hideous goo right off. It definitely took some patience to make sure the PVC had been removed from every nook and cranny, but I think it was worth the effort.
So thanks again to everyone for the advice. I will take some pictures and post them soon.

I scrolled down to just see the obverse and thought "hmmm, well that looks fine to me"....then I scrolled further and thought "whoa". Yeah PVC damage. Good to hear you fixed it.

Call it imagination or my tendency to anthropomorphize, but I think she looks quite a bit happier.   There was also what seemed to be the remnants of some sort of adhesive on the reverse, mostly on the rim and wings. It was a brownish-gold color and had a bit of thickness. It also lifted off fairly readily to the same process.

Huge improvement. I would give it a couple more rinses or soaks in fresh acetone to be sure that every last bit of the green goo is gone, but I'd say you've saved that coin!
