I "Think" it's called a binary note. Not sure if it'd be worth more than FV with the folds and stuff.
For $1.00 I'd say it's a keeper. Neat numbers and you won't get any interest in the bank with it. Nice find.
Sorry, Didn't mean to come off rude (if I did). Liek tommy said, I'd keep it in my collection since you only paid $1 for it. I think I have one lying around somewhere that is all 3's and 2 9's.
It's absolutely a keeper!! Could you get much money over face value for it? Probably not. But it is still really cool.
It's a binary and a near solid, they bring a premium but as to how much IDK...probably what someone is willing to pay. It's definitely a keeper and I would go as far as getting a holder for it. P.s Nice find Lucky
