Yonkers, New York. 1902 Plain Back $20 Fr. 650. The First NB. Charter #653. PMG Very Fine 20. A Plain Back $20 from the highly collectible FNB of Yonkers, NY, this note retains some crispness and reasonably decent eye-appeal for the grade. Some light staining is still evident on the back. The top margin is tight, but just clear of the design. An August 2006 sale brought a bid of $431.25. PMG comments "Stains Lightened."
