Paul I Poltina (1/2 Rouble) 1797 CM-ФЦ XF Details (Scratches) NGC, St. Petersburg Mint, KM-C99.1. A scarce coin with loads of detail that, if not for its imperfections, would come with a significantly higher estimate. There are three scratches at 5 o'clock, 7, and 11 primarily. Still, very collectible in the observed grade.
Estimate: 1000-1500 USD
