Earlier quoted context omitted.
One of the reasons why I changed banks. My new bank has a coin counting machine in the lobby, you throw your coins in, it consumes them, and gives you a slip that you take to the teller. As I understand it, coins are considered a government service. Banks and retailers pay to deal with them. Buying them from the public for face value actually saves them money.
It's so easy to use coins, pennies included, in day-to-day transactions I never accumulate any. Accumulating pennies or other coins is a concept I don't understand. You can spend up to 4 pennies in any purchase you do, and if you don't can't never receive more than 4. For nickels, dimes, and quarters, the maximum is smaller.
*You don't think I'd go into combat with loose change in my pocket, do you?"
But I must admit that I never formed the habit of bringing change with me when I go somewhere. So it piled up at home. The quarters were easy: They got saved for parking, laundry, etc. But I ended up with a sack of pennies that I finally cashed in at the bank.
