Czech koruna

The koruna, or crown (sign: Kč; code: CZK, koruna česká), has been the currency of the Czech Republic since 1993. The koruna is one of the European Union's eight currencies, and the Czech Republic is legally bound to adopt the euro in the future. The official name in Czech is koruna česká (plural koruny české, though the zero-grade genitive plural form korun českých is used on banknotes and coins of value 5 Kč or higher). The ISO 4217 code is CZK and the local acronym is Kč, which is placed after the numeric value (e.g., "50 Kč") or sometimes before it (as is seen on the 10-koruna coin). One crown is made up of 100 hellers (abbreviated as "h", official name in Czech: singular: haléř, nominative plural: haléře, genitive plural: haléřů – used with numbers higher or equal to 5 – e.g. 3 haléře, 8 haléřů), but hellers have now been withdrawn from circulation, and the smallest unit of physical currency is 1 Kč. In 1892, the Austro-Hungarian krone replaced the gulden at the rate of two kronen to one gulden (which is also the reason why the 10 Kč coin had been nicknamed pětka or "fiver" - and has been in use in informal conversation up until nowadays). The name was suggested by the emperor, Franz Joseph I of Austria. After Austria-Hungary dissolved in 1918, Czechoslovakia was the only successor state to retain the name of its imperial-era currency. In the late 1920s, the Czechoslovak koruna was the hardest currency in Europe. During the Second World War, the currency on the occupied Czech territory was artificially weakened. The Czechoslovak crown was restored after the war. It underwent a highly controversial monetary reform in 1953. The Czech koruna replaced the Czechoslovak koruna in 1993 after the dissolution of Czechoslovakia. It first consisted of overstamped 20 Kčs, 50 Kčs, 100 Kčs, 500 Kčs, and 1,000 Kčs banknotes, and a new series was properly introduced in 1993. In November 2013, the Czech National Bank (ČNB) intervened to weaken the exchange rate of the koruna through a monetary stimulus to stop the currency from excessive strengthening.
