RUSSIA. Ruble, 1860-CNB OB. St. Petersburg Mint. Alexander II. NGC MS-60. KM-Y-25; Bit-71. Not surprisingly surpassed in the NGC census by just two examples, this Mint State crown remains without any evidence of handling or time in commerce, with a deep cabinet tone and charming brilliance observed throughout as well. Given how <strong>RARE</strong> indeed it is to encounter such an impressive piece, we expect the competition for this entrancing crown to be quite robust and spirited. From the Sigma Collection.
