RUSSIA. Ruble, 1739. Moscow (Red) Mint. Anna. PCGS AU-53. Dav-1674; KM-198; Bit-204. Type with five pearls in hair. Rather pleasingly toned and only lightly handled upon the high points, this impressive example offers a great problem-free nature to the surfaces and impressive detailing remaining in the intricate bodice of the empress. From the Sigma Collection.
