well it all depends on a few things. what year and series is it from. what federal district. condition is always very important. those are the major determing fators on its worth. if you can post a specific note or have more info about said note i could probably give you a good idea what it might be worth
serial # BB 06642894 FW C 89 series 1999 It's not uncirculated, but minimally circulated and only 1 corner bent. Big faced Jackson.
Looks as if 3,200,00 notes printed from New York District...(printed in the Forth Worth facility) Unless it is in Gem Condition, I would let it go. Corner bends and light circulation will net you an AU note (in most situations), again this is without seeing it...but generally speaking. RickieB
