The currency used in Russia is called the Russian ruble (RUB). It is represented by the symbol "₽" and is divided into 100 smaller units called kopeks. Banknotes in circulation include denominations of 5, 10, 50, 100, 200, 500, 1,000, 2,000, and 5,000 rubles, while coins in circulation include denominations of 1, 2, 5, and 10 rubles, as well as 1, 5, and 10 kopeks. The Russian ruble is widely used in domestic transactions and is also traded in the foreign exchange market, although it is considered a more volatile currency due to Russia's political and economic situation.
