That note is an above average JIM, definitely a keeper for a while. Do get some mylar sleeves to put your notes in if you don't have any already.
Do take photos of the rest of your stash and post it, both sides. We'll be glad to let you know what you have.
Don't take any of it in to a coin shop until you know more about it. You could end up selling the good stuff for a few dollars and be left with the dregs.
The note you showed us is worth about $8, but they do sell well in UNC condition. I would expect a retail offer of $4 for it at a shop. Not much, but a lot of notes and coins can add up, and nice condition is always in demand.
