What is the Polish currency?
Polish złoty
Between 1950 and 1990, a unit known as the "złoty dewizowy" (which may be roughly translated as the "foreign exchange złoty") was used as an artificial currency for calculation purposes only. It existed because at the time the złoty was not convertible (like most Warsaw Bloc currencies) and its official rate of exchange was set by the government. Additionally several exchange rates existed depending on the purpose of the transaction and who was exchanging; for example, złoty could be exchanged for, say, US dollars at one of several official exchange rates depending on what was to be bought with the hard currency and the entity that was buying. In reverse, it worked when an individual or a business had western currency earnings and wanted (or needed) to convert them into złoty. The exchange rate did not depend on the amount being converted. Visitors from countries outside of the Soviet Bloc were offered a particularly poor exchange rate. Concurrently, the private black-market exchange rate contrasted sharply with the official government exchange rate until the end of communist rule in 1989, when official rates were tied to market rates.
