1974 $50

I know it's somewhat pointless without uploading pictures, but I'm curious if theres value in a $50 I found today. 1974, B51470782A in very good condition; far better shape than most current 50 dollar bills. It has one small ink mark on the top right of grant, appears to be a '4'. It has no major creases, althought it does appear to have been bent off center-to the right of grant. The bend is most apparent at the bottom of the bill, but it doesn't seem to have been completely creased (if that makes sense). There are also a couple small bends in 2 of the corners, but again, not completely creased.

Either way I'll probably snag it. I have a collection of each denomination 'old style' bills, and switch out the one I have when I find an older one in good condition :)
