Reverse The upper part of the reverse features the crown of the Russian Empire. Below it, the denomination (with six-pointed stars on the left and right) and the monetary unit are indicated on two lines: 10 KOPĒEKЪ. Below is a decorative divider consisting of two oppositely directed arrows with five dots between them, forming a cross. Slightly below this divider is the coin's year of issue '1866', beneath which is the abbreviation 'S.P.B.' (Saint Petersburg Mint). Along the left edge of the coin is a laurel branch, and along the right edge is an oak branch. The branches are tied together at the base with a ribbon, the knot of which forms a bow. The entire edge of the coin is surrounded by raised denticles.
Obverse The center of the obverse is occupied by the lesser coat of arms of the Russian Empire – a double-headed eagle. Both eagle heads bear crowns, with a larger third crown between them, all three connected by a ribbon. On the eagle's chest 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 on the left). Surrounding the shield is the chain of the Order of St. Andrew the Apostle. The wings bear the coats of arms (four on each wing): Kazan, Poland, Taurida, Astrakhan, Siberia, Georgia, Kiev and Novgorod, Vladimir. In its right talon, the eagle holds a scepter, below which is the letter 'H'. In its left talon, it holds an orb, below which is the letter 'I'. Together, these letters form the initials of mintmaster Nikolai Iossa. The rim is decorated with denticles pointing towards the center.
