Well, this is not really a circulation find, but as I was driving home tonight from Chicago, I stopped for gas and when I got out of the truck I happened to see something on the ground that looked like money. At first I thought it was one of those fake notes that are used for marketing, so you think you found money but all you found was the address for an oil change place or dry cleaner. So I picked it up and low and behold it was a genuine US $50 note, series 2004A!
