Kopeck

The kopeck, also spelled kopek, is a coin or unit of currency used in Russia and several other countries. It is usually the smallest denomination within a currency system and is equal to 1100 ruble.

The kopeck was first introduced in Russia in 1535 as a result of the monetary reform of the regent Elena Glinskaya. It was historically used in the Tsardom of Russia, the Russian Empire, the Russian SFSR, and the Soviet Union.

As of 2026, it is the currency unit of Belarus, Russia, and Ukraine. The Russian kopeck is also used in the two breakaway states of Abkhazia and South Ossetia. Transnistria, another breakaway state, has its own kopeck. In the past, several other countries had currency units that were also named kopecks as a result of Russian influence.
