Superb banknote. Very low serial number and rare as thus. First Run and a banknote that is a great addition to any collection. The note is superb. The reverse image shows a darker mark on the bottom horizontal, right in the middle. This is not a mark but the security thread that runs through the note. The note is lustrous and vibrant. Great quality. There is a light crease (flick?) top left corner so the grading is AUNC.
