The ruble or rouble (Russian: ????? rubl', plural ?????´ rubli; see note on English spelling and Russian plurals with numbers) (code: RUB) is the currency of the Russian Federation and the two partially recognized republics of Abkhazia and South Ossetia. Formerly, the ruble was also the currency of the Soviet Union and the Russian Empire prior to their breakups. The ruble is subdivided into 100 kopeks (sometimes transliterated kopecks, or copecks, Russian: ????´???, plural: ????´??? or ??????). The ISO 4217 code is RUB; the former code, RUR, refers to the Russian ruble prior to the 1998 denomination (1 RUB = 1000 RUR).

Currently there is no official symbol for the ruble, though the abbreviation ??? is in wide use. Various symbols have been put forward as possibilities, including: "??" (cyrillic for "RR"), an "R" with two horizontal strokes across the top (similar to the Philippine peso sign) and an "?" with a horizontal strike.

The amount of 10 rubles (in either bill or coin) is sometimes informally referred to as a chervonets. Historically, it was the name for the first Russian 3-ruble gold coin issued for general circulation in 1701. The current meaning comes from Soviet golden chervonets (????´????? ??????´? ?????´???) issued in 1923 that was equivalent to the pre-revolution 10 gold rubles. All these names are obsolete. The practice of using the old kopek coin names for amounts in rubles is now not very common. In modern Russian slang only these names are used:

* 5 rubles
* 10 rubles
* 50 rubles
* 100 rubles
* 500 rubles
* 1000 rubles
* 500,000 rubles
* 1,000,000 rubles

1947 - 1961

Following World War II, the Soviet government implemented a confiscatory redenomination of the currency to reduce the amount of money in circulation. This only affected the paper money. Old rubles were revalued at one tenth of their face value.

1961 - December 31 1997

The 1961 redenomination was a repeat of the 1947 reform, with the same terms applying. The Soviet ruble of 1961 was formally equal to 0.987412 gram of gold, but the exchange for gold was never available to the general public. Following the breakup of the Soviet Union in 1991, the ruble remained the currency of the Russian Federation. New set of banknotes was issued in the name of Bank of Russia in 1993. During the period of hyperinflation of the early 1990s, the ruble was significantly devalued.

January 1, 1998 -

The ruble was redenominated on January 1, 1998, with one new ruble equalling 1000 old rubles. The redenomination was a purely psychological step that did not solve the fundamental economic problems faced by the Russian economy at the time, and the currency was devalued in August 1998 following the 1998 Russian financial crisis. The ruble lost 70% of its value against the U.S. Dollar in the six months following this 1998 Russian financial crisis.

In November 2004, the authorities of Dimitrovgrad (Ulyanovsk Oblast) erected a five-meter monument to the ruble.

The first coinage after Russian civil war was minted in 1921 with silver coins in denominations of 10, 15, 20 and 50 kopeks and 1 ruble. Golden chervonets were minted in 1923. These coins bore the emblem and legends of the RSFSR. In 1924, copper coins were introduced for 1, 2, 3 and 5 kopeks, together with further silver 10, 15 and 20 kopeks, 1 poltinnik (50 kopeks) and 1 ruble. From this issue onwards, the coins were minted in the name of the Soviet Union. Copper ½ kopek coins were introduced in 1925. The 1 ruble was only issued in 1924 and production of the poltinnik was stopped in 1927, while the ½ kopek ceased to be minted in 1928. In 1926, aluminium-bronze replaced copper in the 1, 2, 3 and 5 kopeks and, in 1931, the remaining silver coins were replaced with cupro-nickel. This coinage was unaffected by the redenominations of 1947 and 1961. However, 1961 did see the introduction of new coins, with 1, 2, 3 and 5 kopeks in aluminium-bronze, and 10, 15, 20 and 50 kopeks and 1 ruble in cupro-nickel-zinc. In 1991, a new coinage was introduced in denominations of 10 and 50 kopeks, 1, 5 and 10 rubles. The 10 kopeks was struck in brass-plated steel, the 50 kopeks, 1 and 5 rubles were in cupro-nickel and the 10 rubles was bimetallic with an aluminium-bronze centre and a cupro-nickel-zinc ring. After the end of the Soviet Union, the Russian Federation introduced coins in 1992 in denominations of 1, 5, 10, 20, 50 and 100 rubles. The 1 and 5 rubles were minted in brass-clad steel, the 10 and 20 rubles in cupro-nickel and the 50 and 100 rubles were bimetallic (aluminium-bronze and cupro-nickel-zinc). In 1993, aluminium-bronze 50 rubles and cupro-nickel-zinc 100 rubles were issued, and the material of 10 and 20 rubles was changed to nickel-plated steel. In 1995 the material of 50 rubles was changed to brass-plated steel, but the coins were minted with the old date 1993.

In 1918, state credit notes were introduced by the R.S.F.S.R. for 1, 3, 5, 10, 25, 50, 100, 250, 500, 1000, 5000 and 10,000 rubles. These were followed in 1919 by currency notes for 1, 2, 3, 15, 20, 60, 100, 250, 500, 1000, 5000 and 10,000 rubles. In 1921, currency note denominations of 5, 50, 25,000, 50,000, 100,000, 1 million, 5 million and 10 million rubles were added.

In 1924, state currency notes were introduced for 1, 3 and 5 gold rubles. These circulated alongside the chervonets notes introduced in 1922 by the State Bank in denominations of 1, 3, 5 10 and 25 chervonets. State Treasury notes replaced the state currency notes after 1928. In 1938, new notes were issued for 1, 3 and 5 rubles, dropping the word "gold".

In 1947, State Treasury notes were introduced for 1, 3 and 5 rubles, along with State Bank notes for 10, 25, 50 and 100 rubles.

In 1961, new State Treasury notes were introduced for 1, 3 and 5 rubles, along with new State Bank notes for 10, 25, 50 and 100 rubles. In 1991, the State Bank took over production of 1, 3 and 5 ruble notes and also introduced 200, 500 and 1000 ruble notes, although the 25 ruble note was no longer issued. In 1992, a final issue of notes was made bearing the name of the U.S.S.R. before the Russian Federation introduced notes for 5000 and 10,000 rubles. These were followed by 50,000 and 100,000 ruble notes in 1993 and 500,000 rubles in 1995. Since the break up of the Soviet Union in 1991, Russian ruble banknotes and coins have been notable for their lack of portraits, which traditionally were included under both the Tsarist and Communist regimes. With the issue of the 500 ruble note depicting a statue of Peter I and then the 1000 ruble note depicting a statue of Yaroslav, the lack of recognizable faces on the currency has been partially alleviated.

The leu ([lew], plural: lei [lej]; ISO 4217 code RON; numeric code 946) is the currency of Romania. It is subdivided into 100 bani (singular: ban). On 1 July 2005, Romania underwent a currency reform, switching from the previous leu (ROL) to a new leu (RON). 1 RON is equal to 10,000 ROL.

Romania joined the European Union on 1 January 2007 and it is expected to adopt the euro in 2014.

On August 15, 1947, a revaluation took place, with a new leu replacing the old one at a rate of 20,000 old lei = 1 new leu. This revaluation, called a monetary reform or stabilisation measure (mica stabilizare, marea stabilizare), was carried out by the Communist authorities with absolutely no advance warning and without the possibility to exchange more than a fixed amount of money for the new currency. This was done in order to depose the former middle and upper classes of their last assets, after nationalization, to prepare for collectivization and to finalize the installation of communism. At the time of its introduction, 150 new lei equalled 1 U.S. dollar.

In the 1990s, after the downfall of communism, inflation ran high due to reform failures, the legalization of owning foreign currency in 1990, and the bankrupt policies of the former communist era, reaching rates as high as 300% per year in 1993. By September 2003, one euro was exchanged for more than 40,000 lei, this being its peak value. Following a number of successful monetary policies in the late 1990s and early 2000s, the situation became gradually more stable, with one digit inflation in 2005.

The Romanian leu briefly held the dubious distinction of being the world's least valued currency unit, from January (when the Turkish lira dropped six zeros) to July 2005. However, the 1,000,000 lei bill was not the highest Romanian denomination ever. This distinction belongs to the 5 million lei bill from 1947.

On 1 July 2005, the leu was revalued at the rate of 10,000 "old" lei (ROL) for one "new" leu (RON), thus psychologically bringing the purchasing power of the leu back in line with those of other major Western currencies. The term chosen for the action was "denominare", similar to the English "denomination", to signify not a conversion, but rather a total reinvention.

The first day brought difficulties adjusting to the new paper currencies and closed ATMs (that needed reprogramming) and forcing a new calculation habit that slowed down shops and annoyed some salespeople and shoppers. The old ROL currency banknotes remained in circulation until December 31, 2006 (coins remained in circulation only until December 31, 2005), but all accounts have been converted starting July 1, 2005. There is no conversion time limit between the currencies. Retailers had to display prices in both old and new currency from March 1, 2005 until June 30, 2006. The appreciation of the leu during 2005 was about 20% against a basket of major currencies.

As of 2006, the revaluation is a potential source of confusion, especially to visitors, since both old and new currency values are commonly quoted. When written, the very large amounts in old currency are usually obvious, but in speaking inhabitants might refer to an amount of 5 new lei as simply "fifty" in reference to its value 50,000 old lei.

In 1952, coins were introduced in denominations of 1, 3, 5, 10 and 25 bani, with the 1, 3 and 5 struck in aluminium bronze and the others in cupro-nickel. In 1955, cupro-nickel 50 bani were added.

In 1960, a new coinage was introduced, consisting of 15 and 25 bani, with 5 bani, 1 and 3 lei coins added in 1963. All were struck in nickel-clad steel. In 1975, aluminium replaced steel in the 5 and 15 bani, with the same change happening for the 25 bani in 1982. Aluminium 5 lei were introduced in 1978.

Following the end of the communist regime, a new coinage was introduced between 1990 and 1992, consisting of 1 leu in bronze clad steel, 5 and 10 lei in nickel plated steel, 20 and 50 lei in brass clad steel and nickel plated steel 100 lei.

As inflation took its toll, 500, 1000 and 5000 lei coins were introduced in 1999, 2000 and 2001, respectively, and were the only coins circulating when the revaluation occurred. They were all criticized for being clumsy and difficult to use. The 500 lei coins were very thick (about 0.3 cm). Despite their small value, it took only a handful of such coins to fill one's pocket. They were also made of poor material and could be occasionally found with bite marks. The 1000 lei coin was considered too small and was also cheaply made, and the 5000 lei coin was not circular (it was a dodecagon). This made it awkward to handle and difficult to use in slot machines, where it was frequently the only coin accepted. The 500, 1000 and 5000 lei coins became worth 5, 10 and 50 bani with the revaluation.

In 1952, the Ministry of Finance introduced notes for 1, 3 and 5 lei, and the Banca Republicii Populare Romane introduced 10, 25 and 100 lei notes. In 1966, the Banca Nationala a Republicii Socialiste Romania took over the production of all paper money, issuing notes for 1, 3, 5, 10, 25, 50 and 100 lei.

In 1991, 500 and 1000 lei notes were introduced, followed by 200 and 5000 lei notes in 1992, 10,000 lei in 1994, 50,000 lei in 1996, 100,000 lei in 1998, 500,000 lei in 2000 and 1 million lei in 2003. There was also a 2000 lei note, introduced in 1999; it celebrated the total solar eclipse that occurred on August 11th, 1999. The final issues of the 2000, 10,000, 50,000, 100,000, 500,000 and 1 million lei were polymer notes.

Notes in circulation at the revaluation were:

* 10,000 lei (became 1 leu)
* 50,000 lei (became 5 lei)
* 100,000 lei (became 10 lei)
* 500,000 lei (became 50 lei)
* 1,000,000 lei (became 100 lei)

In 2005, polymer notes were introduced for 1, 5, 10, 50, 100 and 500 lei. 200 lei notes were added in 2006. The designs of the 1, 5, 10, 50 and 100 lei notes are based on those of the earlier 10,000, 50,000, 100,000, 500,000 and 1 million lei notes which they replaced. The 10 lei bill was redesigned in November 2008 (most of the graphic elements are identical, some of the safety elements were withdrawn, making its safety degree similar the the lower values of 1 leu and 5 lei bills).
