MONGOLIA. 5 Mongo, AH 15 (1925). Leningrad (St. Petersburg) Mint. PCGS MS-61 Brown.
KM-3.1. Sharply struck with flashy luster and hints of original red color between the dentilation at the edge on both sides. Quite RARE in this quality with this being the only MS-61 graded by PCGS with only two examples certified finer.
