I had forgotten about the pennies. Do you remember when they added a penny coin box to coke machines, when they raised the price from a nickel to 6 cents? They spent a lot of money changing those machines, then very shortly raised soda to 10 cents.

Wow, you're right. I had forgotten that little piece of history. How about that little box on the front porch where the milkman put the milk every morning?
