How do I get asphalt off of coins?

Question

I dig up pennies and other random coins when they're embedded in asphalt, and when I do it's all collected on one side of the coin. How do I get the rest of it off? It's impossible to scrape it off.

Answer 1

Try some sort of petroleum solvent.  I sometimes use a little gasoline to take crud off of machine parts etc... Might want to let them soak a little.  Just don't smoke while doing it...ha ha

Answer 2

acetone, Nail polish remover has that in it.

Answer 3

P etrol or kerosine will dissolve the ashpalt in few minutes time if dipped in.Or other solvents like thinner used for paint can be used.
