I found some old pennies that are all green and corroded. Does anyone know how to clean them up?

I heard that soaking them in a batch of Alka Seltzer would get that off. I'm not sure though. (11/13/2008)
I've used baking soda and lemon juice, but anything acidic would work. I agree to check with a coin dealer if you think they may be valuable. (11/15/2008)

Pennies can soak in a vinegar and salt solution. Then wipe clean. Have fun with your penny collection. (11/15/2008)
Baking soda is not acidic, so don't use that if you are looking for an acid solution. I don't know about Alka Seltzer, but I'll bet that it is. Ketchup, vinegar, lemon juice those are all acids.
