Nicholas I gold Proof 5 Roubles 1853 CПБ-AГ PR62 Ultra Cameo NGC, St. Petersburg mint, KM-C175.3, Bit-36, Fr-155. The strike is superb and the green-gold surfaces exhibit only minor contact marks. The fields display the deeply-mirrored quality normally seen only on Proof coins. Very rare in Proof, with only two examples certified by NGC and PCGS, this PR62, and a PR63.
