Back in the 80s i used to use them at the
bar in
Italy. I would get drinks for half
price. I would go to disbursing and get $100 worth of them. You know, there are some $2 bills that are
collectible, but most people don't know what they look like. I think they
still make the $2 bill. The problem is that when someone gets one, they
hoard it like it's made of gold. Hell, they printed the 1976 series note for 20 years.
