Czech koruna is the currency of the Czech Republic since 8 February 1993. Only the 100, 500 and 1000 korun denominations were overstamped, the lower denominations circulated unchanged during this transitional period. Each stamp bears a Roman and Arabic number identifying the denomination of the banknote to which it is affixed (C and 100, D and 500, M and 1,000). * USD/CZK - US Dollar Czech Koruna * Zloty: This Could Send the Czech Krona and Polish Zloty Soaring * Money, Costs and Budget in Prague
