Reverse The center of the reverse is occupied by the coat of arms of the Russian Empire—a double-headed eagle, both heads of which bear crowns. A third, larger crown is placed above and between them. On the eagle's breast is the coat of arms of Moscow—a shield depicting St. George the Victorious on horseback, slaying a serpent with a long spear (the serpent's head is to the right). The shield is surrounded by the chain of the Order of St. Andrew the Apostle the First-Called. In its right talon the eagle holds a scepter, and in its left an orb. Below the right talon is the letter 'A', and below the left talon the letter 'Sh'. These are the initials of mintmaster Aleksei Shneze. Above the eagle is the year of mintage—'1766'. Around the eagle, facing inward, is the text: MONETA•RUBLE•
Obverse The center of the obverse features a right-facing profile portrait of the Russian Empress Catherine II. In the lower section, beneath the portrait, is the abbreviation 'M M D' (Moscow Mint). Along the edge, in an arc starting from the lower left, is the inscription: B•M•EKATERINA•II•IMP•ISAMOD•VSEROS
