RUSSIA. Ruble, 1809-CNB MK. St. Petersburg Mint. Alexander I. NGC MS-61. KM-C-125A; Bit-73. Surpassed in the NGC census by just a small handful of examples, this Mint State survivor yields a high degree of glistening brilliance and a mostly steely gray tone, with some burnished hints observed closer to the peripheries. From the Sigma Collection.
