I think the most was 80 bucks, have found like 10s and 20s here and there.
I was in a CHASE Branch once and obviously the lady(Jewish) that was next to me forgot a wad of cash in the dispenser because when I looked over it was just there. I got nervous thinking it was some kind of ploy from cops or something (had heard cops doing this on subways arresting people buy baiting them with wallets full of money by leaving them on sits and the floor, if they took it and walked away they would get arrested, you know the standup crime fighters the NYPD is... that we have come to know and love had nothing better else to do...
) still till this day I think maybe she really just did forget it, it was at least 500 bucks
