nice!!! its called a binary (only consisting of 2 different numbers)...its definitely worth some money, but i suggest you stash it away and it will gain value steadily! keep it up and hh! [R.I.P. Rich Hartford]
It's a 'keeper'; especially if you can find games of Liar's Poker while you wait for it to appreciate in value. And if you got the bill at a bank, return there and see if you can get more; especially the one with all 7s.

a coworker told me that he has seen $1 bills with good liar's poker hands go for as high as $45 on ebay. i have one with 6 8s on it but plan on keeping it
