I get 2 dollar bills from the bank all the time at FV and use them in day to day transactions but mostly for coffee. I love the look you get from people that had not seen a 2 dollar bill before!
I just watched a couple people on whatnot sell multiple sets of 6 sequential for $5-$20 above face value ($12). All they had to say was come on chat these are rare. Then boom $20-$30 $40 bids for sequential two-dollar bills they got from that morning. Smart guys
