Anyone try it?
Not looking for a huge acetone debate here LOL. Just want to know how were, if any results you've had.

It's good for two things:
1) Rinsing off very light surface debris, i.e. dust, threads, etc.
2) Dehydrating the coin prior to storage.
I use acetone on EVERY coin I put into an airtite. Just a quick rinse on both sides.

If you put Copper coins in acetone and leave it there for a long period of time, an amazing thing happens. And the period of time could be as much as 10 years or more.
NOTHING.
There was a typical story on the internet some time back about Copper coins in Acetone. It was supposed to explain how the Copper would acutally dissolve under certain conditions. Supposedly you place a Copper coin in Acetone, in a clean jar, seal shut, place in the Sun and the Copper coin would vanish. I tried all that but was never able to find the correct Sun so my attempt never worked.
I once put Copper coins, Nickels, Silver Dimes and a Quarter in Acetone all at the same time. That experiment did get some odd results. Other than silly stuff, Acetone just doesn't do much to anything metal.

I tried all that but was never able to find the correct Sun so my attempt never worked. The copper doesn't vanish. Over an extended period of time with constant exposure to bight light it is possible to see, with a microscope, a small reaction with the copper. So you MIGHT be able to consume the copper this way if you continued the experiment for several hundred years, and periodically refreshed the acetone. On human lifespan time scales acetone doesn't visibly affect copper. Some people say that it can affect the color of copper but the only time I have ever seen it do so was when the copper had already been artificially colored and the acetone removed the coloring agent.

Shall we begin a CoinCommunity acetone bath for the futures future members to be awarded as a contest prize?

On human lifespan time scales acetone doesn't visibly affect copper. Speak for yourself. I plan on redoing this experiment and waiting that several hundred years for the results. If nothing happens, I'll let you know.  One of my many experiments with coins in Acetone was placing several varieties in Acetone and allowing to stay there for an extended time.  Never did figure out if it was the dirt or something on some of the coins that did create the differences you see here. Problem with this was I forgot to photo the before and this is the after. All of these were together in the Acetone. Edited by just carl

And when you rinse, don't forget to use distilled water, since tap water has minerals and chemicals in it.

When you rinse, don't use water at all. Use fresh acetone. Half the point of acetone is that it removes any moisture and then evaporates completely without needing to be rinsed off.

Thanks Thad! Any advice on verdi-care and steel cents? Not very effective, I wouldn't bother. Steel cents are so cheap they are very rarely worth the effort of conservation. You buy a complete PDS set in MS grade for next to nothing. |

You may wanna be careful Carl. Someone may follow your "advice" one day.
