pennypincher1 Valued Member Canada 67 Posts	Posted 08/21/2017 7:07 pm I have been lucky to find a 1998 Wide AM Lincoln. I was unlucky to find a small but notable verdigris spot just under the bust, the coin is a good VF. What I need to know is how long should I leave this coin in acetone, don't want to spoil this once in a lifetime find. The coin came out of a roll from Ketchikan, Alaska.

dd27 Pillar of the Community United States 666 Posts	Posted 08/22/2017 12:16 pm Thank you Biokemist6. I I posted the other links for general information about removing surface debris from copper coins, but I should have been more specific about my purpose there. Mark Report this Post to the Staff
