Fr. 350. 1891 $1 Treasury Note. PMG Gem Uncirculated 65 EPQ. Serial Number 8. This note will pair well with the 1891 $2 we are also offering, which happens to feature the same low serial number of "B8." This flashy Gem boasts exceptional appeal of the Open Back design which showcases detailed lathe work in dark green ink. The paper remains bright and helps to pop the darkly inked design. Wonderful punch through embossing is noticed through the third party holder, adding to the eye appeal of this exceptionally well preserved Ace.
