Fr. 1187. 1922 $20 Gold Certificate. PCGS Currency Gem New 66 PPQ.Locating high-end Gem examples of this $20 Gold Certificate design is quite the task. Seldom does this 66 PPQ grade appear at auction and this trait is confirmed with PCGS Currency having graded just eight pieces at this level with four finer. As popular as this type is, the supply simply cannot satisfy the demand.
