Probably been covered before, but would a brief acetone dip be helpful for a few of my Buffalos that appear to have some organic residue?

It certainly will not harm them to try. Just make sure the acetone is the purest you can buy, and remember it can be nasty(flammable, etc.)

Acetone has never harmed any coin I used it on.

I apologize for the newbie question, but would you just dip them in? Wipe the residue away? Air dry, blot dry, etc?
What is standard procedure for this?

You dip the coin quickly and wipe it off lighty with a white towel don't use a tissue! It can harm the coin if wiped carelessly

Hey there Okie, you may want to look at this topic which has a very good example of how to clean a coin using acetone. Super Dave and a couple of the other guys have some very good information: https://goccf.com/t/15797 |

don't wipe it. let it air dry. wiping the coin will leave very small scratches that will effect the value.
Gary too

And make sure to rinse it with distilled water so there is no residue in the water itself that will stick to the coin. Put the coin on a towel and use a hair dryer. That was what I recall reading about Acetone. And use it in a well ventilated area.

Won't acetone leave a film overtime on the coin? Or does that distilled water prevent that from happening?

You won't believe this story. I took your advice and gave my nearly blsck 1915-D Buffalo a dip in acetone. I won this one on ebay and paid $11.50. It is a VF coin, but went cheaply because it is so dark. After dipping I looked at the mint mark again and it is an S, not a D. That increases the value by over twice and makes it over a $100 coin. Best of all I didn't have that date! Now I've got to find another D, but that will be much less expensive. Mintage numbers 1915-D - 7,569,000; 1915-S - 1,505,000. Who knows what wonders lurk under all that carbon? On the other hand the acetone only took off the really layered stuff on the raised areas - it is still a very dark coin. |

As long as the acetone is pure, it will not leave a film since it completely evaporates at room temp. I generally do a double dip- let soak in acetone for a while, let it evaporate, and then a final rinse in fresh acetone. I never even rinse with distilled water since that can leave water spots  The water factor is the reason why acetone is used over ethanol(grain alcohol) or isopropanol(rubbing alcohol)- those both have a percentage of water content while acetone does not.

I strongly suggest you follow the link as noted by OldDan to the post of Acetone usage. If not, remember to use in a well ventilated area, away from flamable substances and don't breath the fumes. Also, the use of the distilled water is for the removal of any possible residue either caused by the Acetone or by just dirt in the air as this dries. Note that Acetone is extreamely great as a solvent and may also suck in dirt from the air as it evaporates leaving the contaminate on the coin. In addition, if the Acetone has disolved some of the substances in the container it was in, that to will be left on the coin. Always rinse with distilled water and BLOW DRY with a hair type dryer. AND not on a hot setting either. Heat on any coin can also increase air substances readtions with metals. DO NOT EVER wipe coins with anything.
The primary thing when using Acetone or any cleaning agent is to use only glass. A class plate, glass utinsils for removing or adding the coin to the solutions. And also, clean those glass items with distilled water. The reason is obvious. Metal pans, pots, utinsils such as tweezers, your hands, all contain additional contaminates that may and will be left on your coins.
Again, I do believe you should read the post that OldDan mentioned.

Just pour it out on the sidewalk, or concrete driveway. It will evaporate away in just a minute or so. (The more surface area the faster it will evaporate.) |

How do you dispose of the used acetone? Pour it in a neighbor's, you don't like, garden. Or if they smoke, put it in their ashtray.  Just kidding. Be careful puting it on a sidewalk if there are people around that smoke. |
