The Ruble

As we all know, Russians use the Ruble as their form of currency. A number of other Eastern European countries use the Ruble as well as Russia, however they are mainly comprised of former members of the Soviet Union.  The name Ruble derives from either piece chopped off of a silver ingot or the seam created when the silver is cast into a coin.  The Ruble has existed since 1710, at which time a currency reform was undertaken and resulted in the development of the Kopek as a lesser coin than a Rubel.  The Kopek is a 100 Rubels.  1 Russian Rubel = 0.021 US Dollars.
