The A1 is the reserve bank code (Boston). I don't know about the G1, G2. BTW, it's not necessary to post the same thing 3 times.
Ten Dollar Bill, Serial# IA140---96A Series: 2006 This bill has traveled at least 648 Miles in 131 Days, 21 Hrs, 52 Mins at an average of 4.9 Miles per day. It is now 648 Miles from its starting location
but isn't the whersgeorge stamp from some federal agency and its a first print on the first page? I think I might keep it
Where's George is in no way a federal anything. Just a bunch of jokers defacing money (sometimes collectible money) because they aren't content enough with a database that makes possible the novelty that is WheresGeorge. Those stamps render bills nearly worthless IMO as collectibles.
have you ever seen a wheresgorge.com bill star note ? it is interesting to see where the bills start out at and how far they have traveled. I have entered about $70 dollars with the wheresgeorge.com stamp on them found in circulation and not created from me. none of them had star notes or low serial numbers. I do understand why currency collectors frown upon it.
