In the centre the relief image of the National Coat of Arms of the Russian Federation, above the semicircular inscription along the rim THE RUSSIAN FEDERATION framed on both sides by ornamental elements of doubled rhombuses, in the lower part of the disc, at the edge the horizontal inscriptions BANK OF RUSSIA and 25 RUBLES, the date 2021 under it, over it to the right the mint trade mark.

The two main elements of Russian state symbols (the two-headed eagle and the mounted figure slaying the dragon) predate Peter the Great. Today, however, the official description does not refer to the rider on the central shield as representing Saint George, mainly in order to maintain the secular character of the modern Russian state. The imperial crowns on each head stand for the unity and sovereignty of Russia, both as a whole and in its constituent republics and regions. The orb and scepter grasped in the eagle's talons are traditional heraldic symbols of sovereign power and authority. They have been retained in the modern Russian arms despite the fact that the Russian Federation is not a monarchy.

The Chukchi, or Chukchee are an indigenous people inhabiting the Chukchi Peninsula, the shores of the Chukchi Sea and the Bering Sea region of the Arctic Ocean within the Russian Federation. They speak the Chukchi language. The Chukchi originated from the people living around the Okhotsk Sea. According to recent genomic research, the Chukchi are the closest Asiatic relatives of the indigenous peoples of the Americas as well as of the Ainu people.
