Nicholas I platinum 6 Roubles 1832 СПБ, Crowned double-headed Imperial eagle / Date and value in circle, Bitkin 58 (R2), Fr-159, Proof 65 Cameo NGC. Heavily frosted devices, with near-flawless, deeply mirrored fields and a superior strike. A very rare issue, especially so in this Gem condition, with an original mintage of only 1,502 pieces. Undoubtedly, only a tiny percentage of this mintage survive, as most were melted. The finest of two examples certified by NGC (the other is 61).From The William Jacob Collection, Part I.
