Guess what? This is the only known FRN radar/error combo US dollar from era 1928 to 1963. In addition to that radar/error note, I also bought two notes that are BOTH STARS and FLIPPERS plus they are MATCHING and that's a BONUS. This $1 1963 series was featured and used as a sample on this website < https://oldcurrencyvalues.com/flipper_serial_number/ > but I don't know why the image is not visible now. This last one is also a flipper star note with a serial of BB00069000*. I like that when you say out loud the prefix letters "BB" you sound like you are saying "BABY" and "69" is what people do to make a cute baby LOL. Most of the time parents call their baby their "star" and that means a special one!
