I've been collecting coins and paper money for 20 years. I don't spend much money on paper so i have tons of stars and a few others things. Well when i looked at my change i saw serial number 45554554. One digit higher and it would have been a binary repeater. Still awesome. I also caught myself from putting a star note in the vending machine at work last week. Thought i was gonna lose it for a minute.
Something tells me this would have been funny to see. Before I was a collector, and probably still, I would laugh at someone beating on a vending machine yelling, "NO! NO! Give it back! Givit back! Give it ba-a-a-ack!" Anyway, congratulations!
