Alexander III Proof Poltina 1885 CПБ-AГ PR63 Cameo NGC, St. Petersburg mint, Bitkin-53 (R1), KM-Y24. Sparkling, fully-mirrored fields, with light green patina and boldly struck devices. Only minor reverse marks are noted and the overall appearance is much nicer than one might expect of the grade. An extremely rare issue, with only 511 examples noted as being struck. The Proof strikings are extremely rare. We note only two Proofs sold in recent years, (1) Sincona auction 24, October 14, 2015, sold for $32,322, and (2) Russian Auction House auction 48, December 3, 2016, sold at $24,940. Only this single example has been certified by NGC, and PCGS.
Estimate: 15000-20000 USD
