Alexander III Rouble 1883 CПБ-ДC MS66★ NGC, St. Petersburg mint, KM-Y25, Bitkin-43. An utterly brilliant and stunning piece, full of boundless luster and enchanting argent surfaces. Wholly worthy of its star designation. A similar example in Gorny & Mosch sale 173 (October 2008) realized a hammer of €9,500.
Estimate: 4000-6000 USD
