Estonian kroon Estonian kroon The kroon (sign: kr; code: EEK) was the official currency of Estonia for two periods in history: 1928–1940 and 1992–2011. Between 1 January and 14 January 2011, the kroon circulated together with the euro, after which the euro became the sole legal tender in Estonia. The kroon was subdivided into 100 cents ("senti"; singular "sent").

The kroon succeeded the mark in 1928 and was in use
