I obtained a group of Kennedy halfs (clad) and I believe they were stored improperly. ALL including proofs have a tone to them and a disgusting milky haze from the moisture and 2x2 mylar holders... I want to remove the haze and start another book.
Being that its clad coins will MS70 work? Do I need to use acetone? I know the rule about cleaning but these coins need a bath. I got a great deal and they are all Uncirculated mint.
Thanks

You have an interesting question.
I kind of think that unless the coin is in danger of being eaten up by corrosion that I should leave it alone.
Post a photo of one of them and maybe someone who has tried it can let you know how it will turn out.

Thank you.. it is pretty much for eye appeal. Its your typical haze you see from coin flaps.

If the haze you speak of is brownish at all. It is from being dipped in silver coin cleaner...it turns clad coins brown permanently.

No there is a slight tone, same tone I've seen from proof sets from the mint that are aged a bit but no what I am speaking of is the pvc haze grime.

I bought some proofs from a shop and the guy cleaned the coins in the back but would not tell me what he uses. "Trade secret" he said.

The MS70 should do fine with the haze. I've used it on clads before.

@penny yes it is, its also a coin cleaner for lack of a better word. http://www.amazon.com/MS-70-oz-Coin...p/B000YQBZPEIm pretty sure that links it. Not sure if coins would grade or not after it but I have heard that it will change the color of copper coins. |

Only one of those two substances is an inert chemical, and only one of the two does anything about PVC plasticizer outgassing.
MS70 is a cleaning agent. Any coin you use it on is then cleaned, by definition. The manufacturer calls it a "coin cleaner."
So you can figure what my opinion is of it.

Definitely try acetone FIRST! MS70 would be a last resort IMO. Acetone will not damage the coins but I can't say the same for MS70, so you have nothing to lose with acetone.

No, not even close. MS70 is essentially soap and water, understanding I won't recommend that for a coin either. The Kennedys here need to go into acetone first, to ensure that what Pipewelder is seeing isn't PVC. Beyond that, I suspect any further step will do more harm than good, and if acetone won't remove it, MS70 doesn't stand a chance. |

I have dipped plenty of clad coins and never had one turn brown. First I have heard that one.
But yes, acetone first.
