Hi, I think it hasn't any additional value. US Treasury issues not only a single note, but uncut sheets with few notes (up to 50), If you like to cut a single note from a sheet it will be eligible to pay at face value. The note you posted looks privately cut from such sheet, so only face value.
You can see such sheets details here. https://www.usmint.gov/paper-currency/uncut-currency/
