Ike And Kennedy Proofs, Surface Problems

Tony

Its not likely that any thing will remove the haze on the coins ,, unless its PVC from the flips ,,you could try pure acetone ,,if soaking the coins does not take it off then its likely there to stay .

Temperature variations are an enemy to coins ,,since humidity and temperature seem to go together .



Sorry !

put some of them moisture absorbers in your safe. I have 4 in mine and have never had a problem and it gets to the high 120's here in Tucson with a lot of humidity this year and I have had no problems at all with the haze. if you used the older type flips they could have PVC but the newer one's are PVC free and wont hurt your coins

Thanks all, I have put them in carboard 2x2's. I like them better anyway. I will leave them alone and see what happens. If they tone up nice that would be good,as long as they don;t just look like heII.

Thanks Tony

I agree with Bryan ,,its worth a soak in Acetone just to be sure ,,and then holder the coins ,, at least you can have that bit of peace of mind .

Yep Pure acetone ! Fingnail poish remover has other things added to it .

Be sure and use a glass container to soak the coins in !

Let us know how it goes .

My dealer has the same problem with the proof coins stored for lengthly periods in the plastic flips. His solution is to pour a little ammonia over the coin and rinse , they look beautiful when done. This will take away the haze without damaging the surface in any way. I personally use regular straight ammonia when I have to, he has some sudsy ammonia he uses - either seems to work fine but the sudsy ammonia does not have quite as pungent an odor as the straight stuff.

I've never liked the idea of using ammonia on a coin. It works a similar reason that dipping a coin in a mild acid solution works, it strips the reacted material from the surface and if done enough times it will strip the luster or proof finish away as well. The only difference is that in the dip you are using an acid and with the ammonia you're using a base. (Take chemistry folks, it's very enlightening.)

And if I did use his method I would agree that you should use the straight ammonia and not the sudsy ammonia. The sudsy is that way for a reason. It has a detergent in it and a rinse with that will leave a film on the coin that will attract other dirt and which may itself react with the coin.
