Heres the kennedy. hopefully you can get a decent idea from the pics what im talkin about. I'll snap the others tonite when i get home.

 

Thats is what I had pictured . I can't say with absolute certainty what caused this , but a combination of packaging and storage environment IMHO is likely the cause. Others may have an opposing opinion .

 

That haze should come off in one or two acetone soaks and rinse in warm water.

If the set is still clean there's probably no rush to do anything.

Careful with acetone. It is extremely inflammable and vapors can be explosive.

 

It's removable , but that means breaking the set apart. A quick rinse would likely do wonders, but I'd have a pro do it because I would mess the coin up for sure.

 

I hate breaking the sets apart, but on the other hand, the coins in the sets are worth more broke up than together. Catch22... where can u get acetone anyways if i would decide to seperate the sets?

 

Acetone can be had at any good hardware store, Home Depot, or Walmart.....

 

I'll check into that. How long should i leave them soak? and can i do it to all of the coins including the nickel clad and pennies? then how long should they be in warm water before the pat-dry?

 

I'd suggest contacting Cladking by PM. He knows his stuff....

 

I'm still learning how to do this myself.

Generally it seems any soak over two days is a waste. It's better to get them out and soak them again then continue to wait. It helps a little to slosh the liquid around the coins every once in a while. Don't let the coins move much though when you do.

 

If you use isopropyl on clad be certain to use 91% as water will cause dark spotting.

 

That's sound advice. Your not working with a $100.00 coin here.

 

Well, i took cladking's advice and got some acetone. I dropped a 66 kennedy in it that had heavier tarnish just to see what happens with it. if i like the results, im gonna break the sets apart and stabilize all of em and store them as seperate. I looked up what they are worth seperated, and they are worth more than as a set, so im not loosing by breaking em up. I will post my results on here as i go along. thanks for all the input!

 

ok, so im happy with the results of the 66 circulated kennedy. so im getting ready to cut apart the mint sets and start workin on them. i will take before and after pics to post on here so you all can see what the outcome was instead of me trying to explain it.

 

this is after a 24 hour soak in acetone. i really wish i would have taken a before pic. But it looks ALOT better. i can't get the shinyness to come throu on pics. The 68 kennedy out of the Unc. set is in the acetone rite now. At leas there are before pics on that one.

 

well, so far i am pleased with the pennys and dime i soaked in the 91% rubbing alcohol. They came out looking perfect, just like new. However the kennnedy in the acetone...not so much.. looks just the same as it did before. so, talking a risk, im gonna put the kennedy in the alcohol too and see if it helps. It don't make sense cause the acetone is a tougher chemical than the 91% Iso alcohol... guess we'll see. pics tommrow.

 

That coin has definitley seen better days!!

 

I agree fully. but you should have seen it before.

 

I really prefer a mixture of solvents. But it is imperative that you don't use water or allow the water from 91% to accumulate to much.

I normally leave them in only two days at a time and then rinse in warm water and dry. If they need another soak then go up to three more times. If they're still bad after four soaks then it's mineral oil.
