Several years ago I regularly registered U.S. dollar bills at the Where's George? website. The idea was (is) that I would stamp the bill with special instructions about the website, where the next owner could enter the serial number of the bill and thereby update its whereabouts. I did this for thousands of bills, but then stopped doing it in 2004 or so. At one time I was one of the top Where's George users, and I even attended a 'meeting' of Atlanta-area Where's George? users (yes, I am that exciting!). It turns out that most paper bills in the U.S. are removed from circulation after just a few years, so the chances of a bill still being out there after 3-4 years is quite small.
Well, today I received an email from Where's George? notifying me that one of my old bills was recently entered. Here's the link to the actual record, but I've also posted a screen shot of the information below. If you look at the bottom entry, you'll see that I entered this bill in Atlanta back in 2000, but the bill is still out there eight years later. It's been to Aruba and Puerto Rico according to the notes. And now it's stuck in New Jersey, where's it been sitting for three years.
Since 1984 Australia has used $1 and $2 gold coins instead of paper bills, so I won't be tracking money here. There are $5, $10, $20, $50, and $100 bills. Each is a different colour, which means there is little confusion when I go digging for money in my wallet. Still, I wonder what the chances are that one of my Aussie dollars will end up in Mendham, NJ some day.
