I got a $5 bill in change for a purchase on Sunday, and stamped on the bill was a “See where this bill has been. Go to wheresgeorge.com.” I’ve always wondered where bills travelled and how long they took, and so I went to the site. It’s pretty cool. I put in the bill’s denomination, series, and serial number and was able to see it’s history. I also added an entry for the bill.
If you are curious, you can see where this bill has been.
