I'll be honest with you upfront. Paper is not my specialty. $100.00 is alot of money. I personally couldn't afford to hang on to that bill. If it were in better shape....I would. The pencil mark and the ragged bottom of the bill I believe will prevent you from getting much over face value for that bill. But do wait for others to chime in.
FYI. The dates on paper money don't change every year like on coins. Yours is a "series of 1934A". They start out with a date, 1934. If they change a signature on the bottom of the bill, it becomes 1934A, then B etc. until they decide to change the date. There were 5 series dated 1934. 1934,1934A,1934B,1934C,1934D. The next series is dated 1950.
Yours was probably printed much closer to 1934 than 1950. There is probably information available somewhere as to what months and years each series was printed...I just don't have it in front of me at the present. Oh
