Lote 31476. Nicholas I of Russia gold 20 Zlotych (3 Roubles) 1840 СПБ-АЧ AU53 PCGS, St. Petersburg mint, KM-C136.1, Fr-111. Mintage: 5,473. A popular low-mintage date from this fleeting series and one we've only handled twice previously. Only mild surface friction establishes the grade, while the majority of the engraved devices remain fully intact. Very rare, and an offering that doubtlessly will be met with keen bidder interest.
