Russian ruble
The ruble or rouble (рубль) is the currency of the Russian Federation (and formerly, of the Soviet Union). One ruble can be divided into 100 kopeks (копе́йка). The ISO 4217 currency code for the ruble is now RUB; the former code, RUR, is now obsolete.
The ruble has been the Russian unit of currency for many centuries. Regular minting of rubles began in 1704. The first rubles were silver, and some 19th century coins were platinum. The gold ruble introduced in 1897 was equal to 0,774235 g of gold. The Soviet ruble of 1961 was theoretically equal to 0,987412 g of gold. Rubles are no longer linked to a gold standard.
Ten ruble coins are sometimes informally named chervonets (черво́нец). Formerly it was a 3-ruble gold coin and later a 10-ruble bill.
All Russian paper money is currently printed at the state-owned factory Goznak, which was organized on June 6, 1919 and has continued to operate ever since.
