Kopeck

The kopeck, also spelled kopek, is a coin or unit of currency used in Russia and some post-Soviet states. It is usually the smallest denomination within a currency system and is equal to 1⁄100ruble.

The kopeck was first introduced in Russia in 1535 as a result of the monetary reform of Elena Glinskaya, who was serving as regent. 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.
