Who says that pennies aren't really worth anything?  What they are really worth is actually priceless.  They can really piss off your credit card company.  Just ask pastry shop owner Thierry Cahez of San Deigo, California.  He got fed up with the ridiculous fees that they were charging him and they wouldn't let him refinance, so got sweet revenge by paying his $6500 balance with 650,000 pennies.

He loaded up his delievery truck with close to TWO TONS of pennies and went to his local Chase bank to pay his balance. They REFUSED to take them because they weren't rolled.  So, our hero, got them rolled and they STILL refused them!  Eventually they caved, and told him another bank had a bigger vault to take such a LARGE deposit.
