Acetone soak

 

Into acetone, stat. This coin will be destroyed within a year if it doesn't get treated.

 

On various sites I've read of acetone but I have never tried it
Am I using pure or diluted acetone in what percentage?
how long?

 

Pure. Don't worry acetone does not react with metals or natural toning. It just removes organics, and could sometimes affect artificial toning depending on how it was produced.

 

How long do I keep it immersed?

 

20 minutes to 24 hours

 

Acetone - used it on hundreds - literally - of coins.

WalMart - copy/pasted from website:.

"ONYX Professionals 100% Pure Acetone Nail Polish Remover, 16 fl oz" priced 2.48

Don't substitute nail polish remover with fragrance and/or coloring added since these will leave a residue. Pure acetone will not.

Soak time - paint/tape residue/glue normally come off within 30 seconds. When this does not work, I look at them after a few minutes. If it looks untouched or not to my satisfaction I leave in a covered jar so the acetone will not evaporate (smart anyway) it overnight.

I do all of mine in a baby food jar with lid.

Don't put this in direct sunlight and let it sit.

For the technical minded - this acetone is rated/sold as 100% pure although the ingredients list one more substance: the bittering agent denatonium benzoate - the most bitter substance known. The agent is added so some whacko won't try to drink the acetone, but the amount added is so incredibly small that professional chemical standards still rate this as 100% pure acetone.

I let some evaporate in a clear dish before I ever used this. There was no residue - hence the 100% acetone is what I use.

All this is verifiable with research - just google the chemical name.

 

This variety is discussed in an Gobrecht Journal article (Issue#65 3/96) by Tom Delorey. No value given but it is a desirable piece. Have it conserved and slabbed at either NGC (tier fee + conservation charge) or ICG (tier fee only, no charge for conservation).

 

That will be a beautiful coin, once it has a thorough Acetone bath. Nice coin, and too bad it was stored the way it was.

 

I am in Italy

 

Congratulations, beautiful country.

BTW, the Internet is universal. I suggest you go to Google and type in:

BTW = By the way.

 

If you walk over to the paint dept. You can find pure acetone in a can. I recommend buying this as it is 100% pure and less chance of purchasing some product meant for nails.
The cost isn't much more and you are 100% sure of what you're buying.
Plus it's in a quart can in case you need to do the process several times in fresh product.

 

NGC has offices in Germany and Switzerland. Go to ngccoin.it and search for "ngc europe" or send an email to Europe@NGCcoin.com

I can recommend their conservation service NCS from my personal experience. And we all know that a trade dollar should be certified anyway...

 

I agree, buy acetone from a hardware/home improvement store. I soak my coins for several hours in a glass dish with a small glass plate on top as the fumes are toxic and explosive. that coinwill need to have the acetone changed 2-3 times because that is a lot of pvc.

 

Once removed from acetone I let it dry on a cloth?

 

Once removed from the acetone, it'll be dry before you can get it to a cloth. Acetone is extremely volatile - that's why we emphasize the caution necessary when using it - but the good part of that is it'll evaporate from a coin's surface almost instantly without leaving anything behind (as long as there was nothing suspended in it from the soak).

 

Einse it off and pat it dry with a towel. DO NOT RUB!!!
