It has to be lower to be really considered a Fancy Serial # I want to share this webpage with you - http://coolserialnumbers.com/FancySerialNumbers.aspx
I would tend to agree with @paddyman98 and @CamaroDMD , it's not that the serial number isn't low enough, it's the general condition of the note. The note has some really hard folds right through the center portrait, other diagonal folds and really soft corners.
Personally, I would save it even though it might only be worth $20 and just replace it when you find a $20 with a lower serial number =)
