Check out this thread. Last weekend I gave some silver rounds and a Canadian Maple an acetone bath for nine hours. They all had some nasty fingerprints that the bath completely moved! They are still not perfect but a vast improvement. The Maple came out the best. Did look like anything was done with it.
do not reuse acetone after a soak. Acetone is a "total loss" conservation system. Always cover the container, from both a safety and economy standpoint. Bman's concept of leaving the container next to an open doorway is fine unless the wind is blowing in....
That said, one shot glass full of acetone is not going to burn your house down unless you're very diligent in your lack of diligence.
Acetone doesn't naturally penetrate problems on a coin to the same extent that water does - part of the process of successfully using it is the "rinse/swish" step which gets short shrift in most discussions. To that end, soaks of more than a few days are probably useless; I've never gathered a bunch of problem coins in one place to do a controlled test of that idea because if a coin needs to go into acetone, it has a problem you want fixed quickly.
Fingerprints are iffy. The permanence of their adhesion - and the time it takes to become permanent - are affected by the quality of the surface of the coin and its' preparation at the Mint. A little contamination already on the coin will prevent a fingerprint from adhering for a while; the more clean and pristine the surface, the quicker a fingerprint will become permanent.
And keep in mind, acetone is an organic solvent. Non-organic chemical processes - "tarnish" - are unaffected by it.
The one pound silver bullion coins are 3 1/2 Inches in diameter. They would not fit in a shot glass?
My bad. Not used to thinking on that scale.
Point stands about getting them into a container of the right diameter to force the coin into a "reclining" position without it laying flat. In your case, that might have to be a 55gal drum.
It might fit in my shot glass.........
