I had seem somewhere about acetone being used to remove serial numbers on new bills and the painted areas of certain quarters. In a manner of seconds with a q tip I removed a serial and the pink ribbon off a 2006 breast cancer awareness quarte  |

Pure acetone is a powerful solvent. Do handle it with care, and use in a well ventilated area. It can also damage mint state bronze and copper coins, through a photo-chemical reaction.

It is mostly Mint State copper that you need to be careful with. I have had a lot of success with acetone on circulated copper. Acetone also does a good job removing PVC accumulation.

The primary use for acetone is removing PVC and minor debris. To say that acetone is 100% safe is a bit of a misnomer. If silver coins are left too long in acetone, they will discolor to a slight tone of yellow. Acetone will also easily discolor copper and in much shorter order. I certainly wouldn't use it on anything with trace of original coin color.

SPP, when you say it is a photochemical reaction, does that mean it is safer to use acetone on copper in a low light environment? I have always gone to the back yard, which is not low light at all.

I've read that using acetone on red copper under sunlight can tone it purple. I haven't tried this myself, I don't want to mess with acetone right now because there's a lot of static electricity around in winter.

I have never heard of acetone turning copper purple. I don't want any purple coins so someone else can try that. Removing the serial number was literally dipping a q tip in acetone and using it like an eraser. Gone within seconds. I have never used acetone on coins before. I use it for prep work for metal art pieces I create.

I have yet to confirm that but not now, not when I make a bright blue spark when getting my finger near something. It's a fire hazard.
The serial numbers are very easy to remove and if you do it slowly enough you won't damage the bill making it look like there isn't a serial number in the first place.
Acetone can also remove the intaglio.

OK, correct me if I'm wrong on this but wouldn't the use of acetone count as cleaning and therefore decrease a coin's value?
