I've been too embarrassed and lazy (lazy because I don't want to go through the bag and check that none of the pennies is of interest to collectors; it'd take a week!) to haul it off to the bank for them to count. It's all the pennies my wife and I ever tossed into a jar throughout our lives, plus all the pennies her parents and her grandmother ever put into a jar. I'm not kidding, it's a HUGE pile of pennies. Couldn't believe it when I first saw it.
Aha! YOUR family is responsible for the coin shortage! :-)
