Watch List notes:

Nicholas I platinum 3 Roubles 1828 СПБ, Crowned double-headed Imperial eagle / Date and value in circle, Bitkin 73 (R1), Fr 160, Proof 63 Cameo NGC. Nicely frosted devices and deeply mirrored fields with a few minor reverse flan flaws that keep this appealing piece from an even higher grade.

Estimate: 8000.00-10000.00 USD
