Be careful what soap you use . I tried to remove a little dirt with distilled water and dishwashing soap . Cleaned it allright but you could tell .

this is not encouraging. I'm not even sure why one would use acetone. We've gone over this a few times and this would be dipping the coin. I just want to remove some exterior gunk which is not part of the coin.

Maybe I need a cement truck.

Ah - your here. I was worried about you today.

A water pick? I don't have one but it should be easy enough to get one from the Pharmacy.

Yes - that sounds rational...

Acetone is a solvent , dips like I said a few posts down have sulfuric acid , thats what removes the layer of tarnish along with a layer of the coin .
Acetone has no acid toremove the coins surface . Always go to least harsh and move up , starting with distilled water as Doug explained , if that doesn't work try acetone , but 1st on a cheap coin in about the same condition , all soaps have different chemicals in them , try them on cheap coins too .

Silver Acetate is a definite chemical that is commonly produced with silver chemistry, and in fact is involved in film development if I recall correctly. It is photosensitive.

So that is the concern right there. You don't need just acid to upset silver, a ketone esther chemical group is one of the most active ones that you can commonly come in contact with.

THe word acetate does not derive from acetone. Acetone is an organic solvent. An acetate is salt derived from acetic acid. Don't mean to sound "preachy". I guess it is the former teacher in me coming out. Silver acetate cannot form from a chemical reaction between silver and acetone, at least just by dipping silver in the acetone.

 

Hello Ruben,

Several nickels made in 1912 have a wood grain to them or they may develop a brown & honey colored toning over the last 100 years. Sometimes a brown toning can be the result of an acid dip which was not properly neutralized. The nickel can be bright after the dip & then the coin's surfaces slowly turn darker & darker brown. Do you think this nickel (link) may have started brighter & turned brown in the holder?

I know very little about nickels

acetone = ph neutral = good

however the following two will alter the surface of the coin
vinegar = acid = bad
soap = base = bad

Personally I wouldn't do anything at all to this coin as I think it looks great.

 

acetone will react with water and alcohol but I made an error completely.

Ruben

 

Actually it does, but your correct and I made an error.
