Charleston, Illinois. $10 1902 Plain Back. Fr. 624. The First NB. Charter #763. PMG Choice Uncirculated 63.An impressive offering on this Coles County charter with this $10 Plain Back being one of a small group of high grade examples known. Nicely embossed and seemingly all that prevented an "EPQ," designation from PMG is a small stain at the extreme upper right corner tip.
