1928 $100 FRN

This kinda fell into my lap today at face value.

My bank knows that I collect and so occasionally they have strange things come in that they hold for me, and when I got there today the lady asked me if I wanted a 1928 $100 bill. So I said sure!

Now I just have to figure out if it is worth anything. Oh yeah, I also have to figure out how to grade notes!

obverse:



There is slight rippling from the Fed seal to the bottom edge, there is a yellow "X" made by a teller's authenticity checking marker between the Fed seal and Franklin's portrait, there is a very light crease diagonally across the lower left hand corner (completely on the white outside of the printed design), and finally, none of the corners are particularly sharp, although the note is still very crisp.

reverse:


Any opinions on grade and possible value would be greatly appreciated!

thanks,
