The scans attached don't really do the bill justice, seems to pick up parts of the reverse side, but here they are. If I were describing the bill I'd use this description I found one line (see below), except this bill has a large degree of firmness remaining and the crease is in the middle and it's not overly soiled:
FINE (F) - A note with considerable evidence of circulation. Numerous creases and folds, but a small degree of firmness remaining. Usually fairly soiled and the hue and intensity of the colour are slightly reduced. There may be a slight amount of the design worn off along the major creases.
Appreciate any help you can offer - thanks!
