Reverse The central part features the State Emblem of the Russian Empire — a double-headed eagle, its heads crowned with two coronets, a third, larger crown above them. In its right talon, the eagle holds a scepter, and in its left, an orb. On the eagle's breast is a shield with the denomination designation — the number '15'. Around the eagle, along the rim, are 15 counting dots, divided into 3 groups of five dots, also indicating the coin's denomination. Below the eagle, on a stylized ribbon, is the year of mintage — '1775'.
Obverse The center of the obverse is occupied by the right-facing profile of the Russian Empress Catherine II. Along the edge, in an arc from the lower left, runs the inscription: B•M•EKATERINA•II•IMP•ISAMOD•VSEROS (By the Grace of God, Catherine II, Empress and Autocrat of All Russia). Below the portrait are the letters 'D M M', the mintmark of the Moscow Mint.
