Fr. 223. 1891 $1 Silver Certificate. PMG Choice About Uncirculated 58 EPQ. PMG comments "Exceptional Embossing" on this beautiful Martha Ace. Bold blue serial numbers and a small red seal contrast quite nicely with milky white paper. The design details are bold in jet black ink. Flipping the note over reveals a stunning design in hunter green ink, with vibrant blue & red security threads standing out.
