Estonian euro coins entered circulation on 1 January 2011. Estonia was the fifth of ten states that joined the EU in 2004, and the first ex-Soviet republic to join the eurozone. Of the ten new member states, Estonia was the first to unveil its design. It originally planned to adopt the euro on 1 January 2007; however, it did not formally apply when Slovenia did, and officially changed its target date to 1 January 2008, and later, to 1 January 2011. On 12 May 2010 the European Commission announced that Estonia had met all criteria to join the eurozone. On 8 June 2010, the EU finance ministers agreed that Estonia would be able to join the euro on 1 January 2011. On 13 July 2010, Estonia received the final approval from the ECOFIN to adopt the euro as from 1 January 2011. On the same date the exchange rate at which the kroon would be exchanged for the euro (€1 = 15.6466 krooni) was also announced. On 20 July 2010, mass production of Estonian euro coins began in the Mint of Finland.
