RUSSIA. Platinum 3 Rubles, 1828-CNB. St. Petersburg Mint. Nicholas I. NGC MS-63★ Prooflike.
Fr-160; KM-C-177; Bit-73. Mintage: 20,023. An immensely attractive example of this first platinum Ruble date, this piece display fully reflective fields with sharply detailed designs that are evidently frosted, imparting a cameo-like appearance on both sides. Several light diagonal streaks in the planchet on the reverse help to positively identify this coin as the example used by the Standard Catalog of World Coins when illustrating the type.

Estimate: $6000 - $9000
