Going through some old* coins and found some with green discoloration. It's worst on this Ike. * old as in I've had them for many years I'm guessing this is PVC residue I've read about. The coin package is labeled "proof" and I don't remember where I got it... probably was a promo where it was free with a $__ order. But now I'm concerned: I don't remember seeing the discoloration back when I first received it. Should I not trust the packaging of any of the similarly packaged coins I bought 25 years ago? Thanks.
Yup I agree the flip is pvc it has ruined the coin take it out and put in something else to prevent more harm.
I agree, probably PVC damage (if the flip is soft and pliable, it's probably PVC). Toss the flip, give the coin an acetone bath and put it in a safe holder.
Soaked it in acetone a couple times. I was delighted with the results while the coin was wet! Dry it's lost some of its luster at an angle (left side of the obverse, middle of the reverse), although still looks good straight on. some angles. Any chance that more acetone baths will restore the luster? Do PVC flips damage non-wartime Jefferson nickels, too? I'm starting to see green on everything!
Yes pvc flips are dangerous for any coins especially old copper if you still have coins in them take em out
