RUSSIA. 5 Rubles, 1847-CNB. St. Petersburg Mint. Nicholas I. NGC PROOF-65 Ultra Cameo. Fr-155, KM-C-175.3, Bit-29, Sev-453. Mint masters initials are those of Alexander Hertov, who served at the St. Petersburg Mint from 1846 to 1857. A superb Proof of the first full year of the new type showing a more refined Tsarist eagle design and a sleeker typeface on the reverse. Bold cameo contrast between frosted, perfectly impressed design motifs and mark-free, fully mirrored fields create this pale yellow gold coins intense visual appeal. No Proofs of this date have been graded by PCGS, while NGC lists only a PROOF-61 Cameo and this PROOF-65 Ultra Cameo, making this coin the finest graded for the year. An important acquisition as a type coin or for the collector seeking a date set of 5 Rubles in presentation format.
