Fr. 2305. 1934A $20 Hawaii Emergency Note. PMG Very Fine 20. Inverted Overprint Error. A dramatic and rare error with the "HAWAII" overprint on the back inverted, one of the great error notes in the Hawaii series and even in all of U.S. currency collecting. The note itself is attractive, with only average problem free circulation noticed. A novice collector would notice this notes desirability, and advanced collectors will readily appreciate it even more.
