I think that if it cleans up with acetone, would I want a shiny corroded coin? A corroded coin should look like a corroded coin. I vote leave it be. It has 217 year old patina.

The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself in a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat."

True numismaticstudent I'm not looking to shine it up I was just hoping that some of the stuff stuck on the reverse might come off.

Acetone will not "shine" these up or help them in any way. Acetone does not change the color of a coin.

Acetone works best taking dirt and tape residue off.

I wouldn't touch them. Just enjoy them for what they are. It took them over 200 years to get to where they are  |

Acetone removes certain materials from the surface of the coin. If the OPs coin has residue, built up for years or decades that is removed via acetone, it is possible that the previously unexposed surfaces may look shiny in comparison to the exposed, corroded surfaces. That would be a detrimental outcome from acetone treatment.

Good point, NumismaticStudent. Another good reason not to play with history |

Don't see the upside so wouldn't spend any more time on them.

I don't recommend acetone on early copper, especially corroded early copper, unless you plan to treat the coin afterwards. A lot of times, there is a film of oil, gunk, and debris that is actually protecting the surface of the copper from further degradation. When you strip away all of those layers, you leave the raw metal exposed to the environment, and unprotected. If I have a piece of early copper that needs acetone as a solvent, I insist on giving it a Verdi-Care bath afterwards, and then letting it air dry for 24 hours without touching it otherwise. Afterwards, any excess can be (carefully) blotted off and the coin will then be conserved against future damage if stored properly.

I wouldn't touch them. They are well worn and nothing you do can change that. Enjoy them as they are.
