RUSSIA. Soviet Union. 10 Kopeks, 1923. Leningrad (St. Petersburg) Mint. PCGS PROOF-65. KM-Y-80; Fedorin-3П. Surpassed in the PCGS census by just two other examples, this robust Gem offering in proof presents a tantalizing golden-olive tone that is sprinkled rather majestically throughout. Meanwhile, this intense brilliance in the fields and razor sharp strike simply augment its lively character that much more.
