Cincinnati, Ohio. $20 1882 Brown Back. Fr. 504. The German NB. Charter #2524. PCGS Currency Fine 12. Two Brown Back $20s from the German National Bank of Cincinnati are presently shown on the Census - this note makes three. While grading only Fine 12, it remains free from any significant problems, and simply displays some light toning of the paper and some fading of the seal and right signature.
