Hi Judy!
It really depends on the condition of the note and if your not a collector it would be difficult for you to give an accurate grade the best thing to do is post a picture so we could get a better idea of the grade. However here is a rundown of values for different grades Very Good = $125, Fine =$175, Very Fine = $275, Extra Fine = $450, Almost Uncirculated = $575 and Uncirculated = $700. I hope this helps.
