This made my morning.
Wheresgeorge is a ghetto-fabulous site, complete with a cash-register “ka-ching” sound effect. But at heart it’s a fun social experiment. You provide the serial of the bill you found and the zip code you’re currently in, and in return you see all the previous locations the bill has been logged by previous owners. It’s like the analogue version of Jack Dorsey’s vision for Square.
This particular bill originated from a 5th grade class in Gas City, Indiana that is studying money and geography.
