I believe the notes from your set are expected to have glue residue as this is how they were mounted in the binder.
The catalogue price for this set is $24,000.
The coin set is nothing to sneeze are either, there are two varieties for 1954 the regular one $750. and the no shoulder fold 1 cent one $1650.
Judging by your good fortune you have the NSF variety.
$15,000 not a bad offer from a pawn shop, but I'm sure you could do better, just takes a little time
