Center, Colorado. $20 1902 Date Back. Fr. 645. The First NB. Charter #9743. PMG Choice Fine 15.It was 21 years ago that the unique blue seal from Center, CO was offered for auction. When the dust settled, the final bid was $24,000. The year was 1998. This was the same time period when an Indian Territory red seal might struggle to break $6,000. This price result was astounding, even for a rare and highly desirable one bank town. That note, a ten listed as F/VF hasnt been seen since. Here is a second chance for the underbidder and any of the number of new collectors who have entered the market in the past two decades. The First National Bank of Center was chartered in May of 1910. It issued only $155,250 into circulation in the form of 1902 Date Backs and Plain Backs. Just $360 in notes were outstanding on the bank at the end of the National Currency era in 1935. This $20 Date Back displays boldly printed inks and neatly penned signatures of bank officers Fernandez and Jones.
