Fr. 321. 1891 $20 Silver Certificate. PMG Gem Uncirculated 66 EPQ. A top of the pop note with no equals and a piece which will surely catch the eye of all seeking the finest known material available. The overprints are particularly rewarding to look at as the blue treasury seal and vibrant blue serials are deeply embossed into the frost like paper. Picture perfect centering and margins house the deeply impressed design and terrific registration of the face and back. Truly a scare opportunity to secure this popular catalog number. PMG Pop 9/None finer.
