Bethlehem, Pennsylvania. $5 1902 Plain Back. Fr. 602. The Lehigh Valley NB. Charter #2050. PMG About Uncirculated 53. While just over two dozen Plain Back $5s from the Lehigh Valley NB of Bethlehem, PA appear on the Census, only four rise above the VF grade. We are at a bit of a loss to explain the AU 53 grade, as this note is a virtual twin to its sheet mate (s/n 29417 D) which was graded Uncirculated. We see no evidence of circulation whatsoever on this note. It retains full freshness, color and would be a prize addition to any collection.
