I am probably the only person in the world with a stamped 2.00 bill. Way back in the 70,s I believe, the united states reissued the 2.00 bill. Now, you are allowed to get a 2.00 at the post office on the first day of issue and have it stamped with that days date signifying first day of issue. Since the U.S.reintroduced the 2.00 bill it was considered a new issue. So, off to the post office, I tell teller I want a stamped 2.00 bill and she gets one and then puts a actual stamp on it and then stamps it. I just laughed and took it and left.
