孙中山像开国纪念一圆银币。二枚。 两枚皆铸打深峻,底板馀光充沛。同心虹彩包浆,由浅至深,赏心悦目。 CHINA. Republic. Duo of Beautifully Toned "Memento" Dollars (2 Pieces), ND (1927). Both examples exhibit a nice strong strike with bold details and plenty of remaining luster in the protected areas and fields. Lovely concentric rainbow tone extends from the rim into the fields giving both pieces great eye appeal. 1) NGC MS-61. KM-Y-318a.1. LM-49. 2) NGC AU-58. KM-Y-318a.1. LM-49.
