What is Russian money called?

The Russian currency is the ruble, according to the XE website. The symbol for the ruble is ???. The ruble's minor unit is the kopek (?.), which amounts to 1/100 rubles.

The ruble has been used in Russia for around half a millennium. Other countries have used the ruble at various points in history. The ruble became the official currency of Russia in the 16th century, remaining the official currency until 1921. A dramatic decrease in value led to the redenomination of the ruble and the birth of the second ruble, which lasted only a year. The remainder of the 20th century saw third, fourth, fifth and sixth incarnations of the ruble before the final redenomination was issued in 1998.
