I've seen several mentions of rolls of pennies. My daughter had four ammo cans of change given to her by various grandparents and great grandparents, so we go to the bank to cash them in. Since I have an account there, we get to use the change machine for free. I was talking to one of the bank employees and I said something about getting tubes and making her roll them like I did as a kid. The bank employee said it was pointless, because they have to unroll rolled coins and run them through a counter before they can give you folding money or make a deposit of it. There was too much fraud in rolled coins to trust people.
