RUSSIA. Ruble, 1808-CNB MK. St. Petersburg Mint. Alexander I. NGC MS-61. KM-C-125A; Bit-71. An impressive specimen, this majestic crown offers a high level of lustrous brilliance along with mostly argent surfaces that have undoubtedly stood the test of time. A hint of toning is speckled about, but this piece nevertheless wholly enchants. From the Sigma Collection.
