Military Payment Certificate. Series 521. 10 Cents. Replacement. PMG Superb Gem Uncirculated 67 EPQ. Second Printing Replacement. Top Pop at PMG as the only superb gem piece they have encountered. Their Population Report shows that the First Printing replacement is by far the most common of the three printings. Our previous nicest example sold was a PCGS Choice About New 58PPQ from the Paymaster Collection which realized $734.38 in our 2016 ANA sale. A great note at this grade level.
