Nicholas I platinum 3 Roubles 1828-СПБ MS65 Prooflike NGC, St. Petersburg Mint, Bitkin-73 (R1), KM-C177. Obv. Crowned double-headed Imperial eagle. Rev. Date and value in circle. A stunning example of the first-year issue of this popular series made from platinum mined from the Ural mountains. The fields are fully mirrored, and the devices frosted, giving a sharp cameo contrast. The strike is essentially flawless and both sides display only tiny marks. A Gem example with super eye-appeal.
