The Czechoslovak Koruna was the official currency of Czechoslovakia from 1920 until the country's split in 1993. It was abbreviated as CZK and symbolized by "Kč." The koruna was subdivided into 100 haléřů. After the dissolution of Czechoslovakia, the currency was replaced by the Czech Koruna in the Czech Republic and the Slovak Koruna in Slovakia. The koruna played a significant role in the economic history of the region, reflecting the country's political and social changes over the decades.
