I don't know if this would really be considered a "find" since I never received any of these bills in change, but I thought I would post anyways.
I was at my bank today and the teller said "I was just thinking about you" I asked why and she told me they just had a bunch of old 100's deposited in the atm. I asked to see them and found 7- 1937 $100's, a 1954 devil's face 100, and a bunch of 2's and 1's. Needless to say I bought them all.
Nothing of interest in the ones, but I found 2 consecutive AUL's in ef+ and 2 consecutive AUK's in au.
Not a bad bunch of notes for face value I must say:)
