Benjamin Franklin said that a penny saved is a penny earned, but these days a penny is close to worthless.
However, if you save a lot of pennies, you could roll them up and exchange them for a few bucks.
The most I ever saved up at once was thirty bucks, and that had been kinda heavy.
Instead of wasting all that effort, I now stick a pound of pennies in a sock, and then whallop people on the head with them.
The most I’ve gotten that way was two hundred bucks from a guy coming out of the bank.
