The Polish Zloty


The Polish zloty (before 1995 - PLZ; then changed to PLN, zł) is the official currency of the Republic of Poland. It is not a freely convertible currency, and its circulation is limited solely to the country’s territory.


The monetary system of Poland used to be complicated and tedious before the zloty appeared. The grzywna, kopa, and grosz (silver coin) were circulating during that period. The latter was subdivided into szóstaks and trojaks. The szóstak comprised six groszy and the trojak - three. 

In the Middle Ages, almost all European states introduced the ducat - a coin minted in Venice - as the means of payment. It appeared in Poland as well. At first, its exchange rate was approximately 12 groszy for one ducat. The Polish began to call it ‘zloty’ (‘golden’) to shorten the name. 

As time passed, the Polish grosz devalued: one ducat cost 30 groszy, and then - 50 groszy. However, the Sejm decided to make the ducat exchange rate fixed (1 ducat = 30 groszy) and introduce the terms of the Polski złoty and the czerwony złoty.

The golden ducat became the czerwony złoty, and after the monetary reform of the 16th - 17th centuries, the Polski złoty obtained the status of the uniform monetary unit. It equalled half of the kopa or 30 groszy.

The first silver zloty was minted in the 16th century. Nominally, it equalled 30 groszy as before, but mass minting entailed the loss of pure silver. The actual weight of the metal in coins was not more than 3.3 grams, which constituted half of their general weight. Therefore, its real value was only 12 groszy, not 30. 

The zloty got a new name - tymf, but people just called it złotówka. Tymf circulated till the last quarter of the 18th century though its introduction created many problems for the Polish financial system. 

The partition of the country in the 18th century led to the appearance of a multitude of money varieties within its territories. The banknotes in enormous denominations of several million zlotys were issued. After the Russian Emperor’s troops conquered Warsaw, the Russian ruble along with fractional coins of the Russian Empire began circulating. Nonetheless, calculations of all the prices were made in zlotys and groszy because the Polish financial system complied with the silver standard at that time. 

The Kingdom of Poland became part of the Russian Empire, and therefore, got the internal currency that circulated within its territory. That was the zloty pegged to the Russian ruble. Besides, the latter could also circulate along with the Polish currency. 

After the Polish Uprising of the 1830s, the Russian government restrained the financial autonomy of the Kingdom, and in 1841, the ruble became the official currency. The only place where zloty continued to be minted and used for payments was Krakow as the free city. 

In 1918, when World War I ended and Poland gained independence, there was the multi-currency circulation of the Austro-Hungarian krone, the German marka, the Russian ruble, and two occupational currencies like the Ostruble and the Ostmark. 

In 1917, the Polish government decided to substitute all money with the Polish marka. The name was analogous to the German marka. That period was advantageous for both economy and finances, but the following events led to depletions of all country’s accumulated resources. Józef Piłsudski, Poland’s leader at that time, got into a war with USSR for the border regions of Ukraine, Belarus, and Lithuania. 

As a result, the Polish marka became sharply devalued due to the significantly increased war expenses along with low taxes. In 1920, after an armistice with the Russian SFSR, the marka devaluation level was even higher. That is why in 1924, the monetary reform took place in the country. The zloty as the official currency of Poland returned with an exchange rate of 2 million markas. 

However, the reform did not deter zloty from further devaluation. Negative economic processes were occurring in the background of coup d'état organised by Józef Piłsudski. The loan provided by the USA and strict financial policy under the supervision of banking experts from the West enabled stability of the zloty and even improvement of its status for the following several years. 

Later, the issues resumed again. After the death of Piłsudski, the military forces gained authority. The only solution in an attempt to make the economy stable was to bring it under state control.

After World War II, Poland joined the socialist way of development. After 1944, the zloty underwent several monetary reforms and denominations because inflation continued to increase. 

Only in the 1970s during a couple of years, some kind of stability appeared. However, in 1980, a devastating economic crisis commenced and led to the shift in power and a new course of Poland oriented to the capitalist model of economics. That was the time when the republic ceased to be socialist. 

The inflation slowed down its rate and became controllable. At the beginning of the 1990s, the Polish economy depicted an unbelievable boost. 

In 1995, the tenfold denomination of the old zloty took place, though the printing of new banknotes began a year earlier and the coin minting - in 1990. The banknotes in denominations from 10 to 200 zlotych and the coins from 1 to 50 groszy were introduced. That series got the name of a new zloty and a new international code - PLN. 

Old money was withdrawn from circulation in 1996, but there was a possibility to exchange them in banks till 2010. 

In 2015, a 500-zloty banknote was added to the existing ones, though it had not been previously planned to introduce it. 

Since 2012, the issuance of modified banknotes began. They gradually substituted all older, damaged, and outworn paper money. 


Zloty banknotes are issued in six denominations from 10 PLN to 500 PLN. Some commemorative notes have been issued as a dedication to various significant events in the country’s lives.

Fractional coins of Poland are minted by the Mint of Poland in nine denominations. There are six denominations for the groszy and three - for the zloty. The denominations of coins range from 1 to 50 groszy (1 gr, 2 gr, 5 gr, 10 gr, 20 gr, and 50 gr). Since 2017, the alloy material has become cheaper. The zloty coins are minted in denominations of zł1, zł2, and zł5. 

The reverse of all coins features the value surrounded by the oak leaves. 

Circulation in the World

Poland joined the European Union in 2004, but its transition to the common currency used to be postponed all the time. In 2016, the country’s government decided to refuse to introduce the euro because Poland was willing to keep its fiscal independence in the future. The zloty will remain the official currency of the republic in the foreseeable future.
