The lev (leva, levove) is the currency of Bulgaria. It is divided in 100 stotinki . In archaic Bulgarian the word "lev" meant "lion".

In 1962, another redenomination took place at the rate of 10 to 1, setting the exchange rate at 1.17 leva = 1 U. S. dollar, with the tourist rate falling to 2 leva on February 1, 1964. The ISO 4217 code was BGL. After this, the lev remained fairly stable for almost three decades. However, like other Communist countries' currencies, it was not freely convertible for Western funds. Consequently, black market rates were five to ten times higher than the official rate .

After the fall of communism, Bulgaria experienced several episodes of drastic inflation and currency devaluation. In order to change this, in 1997, the lev was pegged to the Deutsche Mark (DEM), at a rate of 1000 leva to the Deutsche Mark.

On 5 July 1999 the lev was redenominated at 1000:1 with 1 new lev equal to 1 Deutsche Mark. The ISO 4217 currency code for the new Bulgarian lev is BGN.
Commemorative 1.95583 leva coin

With the replacement of the Deutsche Mark by the euro, the lev's peg effectively switched to the euro, at the rate of 1.95583 leva = 1 euro, which is the Deutsche Mark's fixed exchange rate to euro. Since 1997, Bulgaria has been in a system of currency board and all Bulgarian currency in circulation has been backed 100% by the foreign exchange reserves of the Bulgarian National Bank (BNB). The rate is unlikely to change before the lev's retirement. On 25 April 2005, when Bulgaria's EU accession treaty was signed, the BNB issued a commemorative coin with the face value of 1.95583 leva. The lev was expected to be replaced by the euro on 1 January 2012, however some recent analysis says that Bulgaria will not be able to join earlier than 2015, due to their inflation problems and the impact of the global financial crisis of 2008.

n 1952, coins (dated 1951) were introduced in denominations of 1, 3, 5, 10 and 25 stotinki, with the lower three denominations in brass and the higher three in cupro-nickel. Cupro-nickel 20 stotinki dated 1952 were also issued, followed by 50 stotinki in 1959 and 1 lev in 1960 (both also in cupro-nickel).

In 1962, brass 1, 2 and 5 stotinki, and nickel-brass 10, 20 and 50 stotinki and 1 lev were introduced.

In 1992, a new coinage was introduced in denominations of 10, 20 and 50 stotinki, 1, 2, 5 and 10 leva. All were struck in nickel-brass except for the cupro-nickel 10 leva. In 1997, nickel-brass 10, 20 and 50 leva were introduced.

In 1962, the National Bank issued notes for 1, 2, 5, 10 and 20 leva. A second series, in the same denominations, was issued in 1974. 50 leva notes were introduced in 1990. After the fall of the communist regime, new notes were introduced for 20, 50, 100 and 200 leva. These were followed by 500 leva notes in 1993, 1000 and 2000 leva in 1994, 5000 and 10,000 leva in 1996, and 50,000 leva in 1997.

In 1999, banknotes were introduced in denominations of 1, 2, 5, 10, 20 and 50 leva. 100 leva notes were added in 2003.

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).
