try posting it in the currency bills/notes section, I think this one is more for coins, might get a few more bites over that way.
It should get you a more than a few Slurpys with that crappy serial number. (7-11) Seriously, though, that's a nice pick-up. It should carry a nice premium.
If the note wasn't a star I'd say it would be in the $25 range but since it is a star I put its value at $40+. I am saying that based on my past experience in dealing with three digit serials but what it all comes down to is what a collector is willing to pay. You could bring in more or less but regardless it is a keeper for sure.
