Of course, that was for a close-up of the bill itself which was actually relevant to the plot.
Iirc, there’s nothing stopping a production from simply using real bills, aside from the cost. It’s really only when you see them in bulk that props are necessary. Plenty of shots where someone is counting their money will also use real bills just for simplicity’s sake, but that cash is tightly controlled by the props department and they’ll switch it out for fake bills for general use.
They used an actual $100 bill in National Treasure iirc
