(t) RUSSIA. 10 Kopeks, 1833-CNB HT. St. Petersburg Mint. Nicholas I. NGC PROOF-64+.
KM-C-164.1; Bit-348. An enticing RARITY that does not present itself often, this proof striking offers incredible eye appeal through its gunmetal gray tone and burnished olive toning around the devices. Meanwhile, a great deal of glistening brilliance radiates off from the gleaming surfaces, with the example itself residing at the cusp of Gem status. This alluring specimen represents the only such instance of a proof for the year and denomination in the NGC census.

Estimate: $7000 - $10000
