All ya gotta do is get your hands on one of the 50,000 dollar coins the Philadelphia branch of the US Mint recently released without the words "In God We Trust" on them!
They somehow got past quality control and were let into the money stream, now they're going for $50.00 a pop on ebay.
I say everyone head to the post office and buy the cheapest item you can out of the vending machine while using a $100 bill. That'll give you about $99 dollar tokens in change!
Once you've sold em all on ebay that's a cool $4,950.00. And hey, if it turns out you don't get the misprinted ones? You still got your $99.00.
