Does anyone have any experience with rubber band stains on silver coins?
Will the stain come off with acetone?
Thank you for your replies in advance- Steve

I believe the acetone should work.... Only problem is if the rubber band caused some toning then that will stay there. do you have pictures?

I have that on one of my coins. I was wondering what that was.

there's a good chance that some remnant of the stain will remain. who knows what kinds of rubber or softener/plasticizers were present in the rubber band.

Acetone would remove any actual pieces of degraded rubber that might be still stuck to the coin, but the tarnish stripe left behind will not come off in acetone. Rubber is chock-full of sulfur, and it's this sulfur that has reacted with the silver to turn it black. Regular "toning" on a coin is caused by a similar reaction with atmospheric sulfur. Tarnish remover or "dip" will get rid of the stripe, but the end result will be a dipped coin.

Sap nailed it, both cause and what it will take to remove it.

Not too bad of details though, but why would anybody have a rubberband around a coin?
