Fr. 310. 1880 $20 Silver Certificate. PCGS Banknote Very Fine 20. Bruce - Gilfillan signature combination. Track and Price reports a scant 49 examples of this Friedberg number in their census, which is hardly enough to satisfy demand to collectors. This note is seen with a large brown seal, and two large "X" counters in brown ink below the seal. At right is a portrait of Commodore Stephen Decatur, who served with distinction with the United States Navy. The details of the primary design on the obverse and reverse still offer plenty of appeal for the assigned grade. PCGS Banknote comments "Trimmed, Minor Rust, Minor Splits and Tears."
