Fr. 311. 1880 $20 Silver Certificate. PMG Choice Fine 15. Offerings of this popular type are far too few to satisfy collector demand, and this Choice Fine note is sure to fill a hole in a collection. This Bruce-Wyman signed note displays still dark blue serial numbers, along with a still attractive design. An oversized "SILVER" design is found on the reverse, which was to help instill confidence in the public to accept paper money in the place of coinage. From the Liberty Collection.
