RUSSIA. Ruble, 1757-CNB RI. St. Petersburg Mint. Elizabeth. NGC EF-45. KM-C-19c.3; Dav-1680; Bit-282; Diakov-434. "Dassier" Ruble type. Astonishingly <strong>RARE</strong>, this one year type features an artistic bust of Anna that is supremely attractive. Jacque Dassier came from a renowned family of Swiss medalists, and had prior to this issue worked as an engraver at the Royal Mint in London. He moved to St. Petersburg in 1756, where he lived until shortly before returning to Copenhagen and passing away. This example is deeply toned with an engaging and slightly glossy patination. Light circulation is visible on the highpoints of the bust of Anna and the imperial eagle of Russia, but this example is exceptional in that it does not have lamination or planchet flaws. Ex: Baranova Collection (Christies - Geneva 5/1984) Lot #207.
