1922 $20 GOLD CERTIFCATE MULE NOTE. Serial# K3562607 with the signatures of Speelman/White. Friedberg# 1187. Plate# C15/124. Graded 67 PPQ (premium paper quality) Superb Gem New by PCGS. Superb color on the front and back, excellent centering and deep embossing. This is easily one of the FINEST! The gold certificate was used from 1882 to 1933 in the United States as a form of paper currency. Each certificate gave its holder title to its corresponding amount of gold coin. Therefore, this type of paper currency was intended to represent actual gold coinage. In 1933 the practice of redeeming these notes for gold coins was ended by the U.S. government and until 1964 it was actually illegal to possess these notes (in 1964 these restrictions were lifted, primarily to allow collectors to own examples legally, however the issue technically converted to standard 'legal tender' with no connection to gold).
