589 Extremely rare possibly unique China-Republic Sun Yat-Sen Memorial Medallion Plaque. Overall size, 99mm x 120mm (3 7/8" x 4 3/3"), with a 77.5mm central circle portraying a masterful half-length bust of Dr.
Sun in western civilian clothes, suit, vest, tie and hat. The plaque was at one time likely mounted in a frame with the center roundel displayed behind a protective matte. Lightly toned, and of the greatest rarity. It is a very important medal for collectors who study the history of coins for the Republic of China era. PCGS graded "Authenticity Unverifiable", NGC graded "No Decision". Both grading companies can't render an opinion on first try. As many experienced collectors all know, over time if you submit the same coin couple more times, they might change their opinion when new information shows up.
