Hinkle Posted June 15, 2020 Report Share Posted June 15, 2020 Hi everyone, thought this would be an interesting one. It's the last digit in the bottom serial number the 2. I see stuff like this on a dollar bill, but not a 10 dollar bill. The 2 looks like it's also floating in the position were it's at. Thanks for any thoughts on this.
