its not in all that great a shape.. take a look in the center of the note.. the note has been folded so mkany times, the ink in the portrait is getting thin. Still a nice note IMHO, and a certain keeper if you can afford it.... but it doesnt look to be a real high grade note!
The detraction from the folds is considered a break in the ink away from the paper or (paper break)...as Daggar pointed out, I would think the premium would be minimal if any at all. Traveling in Germany and do not have my book with me.... RickieB
