Henryetta, Oklahoma. $10 1902 Plain Back. Fr. 629. The Miners NB. Charter #10349. PCGS Banknote Fine 12.This is just the second known note to come forward from this rare Okmulgee County bank. Just $187,000 in 1902 Date Backs and Plain Backs were issued from the bank during its 10 year existence. Both of the survivors are rather well traveled $10 Plain Backs. The other known note is recorded as Very Good but has seemingly been very tightly held with no auction records to report. The presently offered example comes boldly printed on still wholesome paper.
