拍品描述： Military Payment Certificate. Series 521. $5. PCGS Banknote Gem Uncirculated 65 PPQ.1^st Printing. The first printing of the $5 denomination for Series 521 is the toughest of that series, and this is a fine example showing great centering and color. Although it is not a top pop, it is close - as PCGS Banknote has graded only one in this grade, and one higher. Of the 77 in all grades that PMG has seen, only four surpass this one. One of the scarcest MPCs in high grade and certain to be a highlight in any collection. PCGS Banknote Pop 1/1 Finer.
