Ok, how long have you been carrying this? :)
I think I got that bill on my last trip to the US, or maybe the trip before that. I remember the cashier joking that this wouldn't be some kind of forged money. And it already looked rumpled when I got it, so ... on a different note, I also have a half Dollar which you usually don't come by that easily either.
Erich loves the odd currency- $2 bills, $1 coins... he's so weird! ;)
