I'm getting my M and M tube ready for our June trip and am wondering...what type of pennies should we take for the Penny Stamping Machines? I've read everything from new to pre-1982--how DO you clean them? I tried vinegar and baking soda and that worked a little, but not much. So, what have you all found to be the best pennies for the machines? TIA
