Welcome to CT @Billy325 By the serial number we can surmise you have a series 1996 New York District $100 note...first year for the large portrait. The serial number is not fancy, so unless the note is CCU, my guess is somewhere around face value. Thanks for the full size photos. Your note also has a counterfeit detection pen mark on the left side.
If you mean the slight wet ink transfer on the back, I have an old $50 note with that same slight wet ink transfer. Unfortunately I think your note is worth no more than $100.
