Haven't seen specific mention of this here so I thought I'd pass it along. There's a picture of a receipt from a bank coin cointer that tabulates "new" and "old" pennies seperately. Someone else in the thread mentions seeing this with coinstar machines.
Interesting. I am going to try an experiment tomorrow. Gonna go to a coinstar machine and the bank counter I always use, put in both types of pennies, and see what happens.
