The 2015 Estonia 2 euro commemorative coin celebrates the 30th anniversary of the European Union flag. The national side features a design chosen by the citizens of the European Union through an online vote, depicting the flag as a symbol that unites people and cultures across the continent. Surrounding the central flag motif are twelve stars, representing the ideals of unity, solidarity, and harmony among the member states. This design reflects Estonia’s commitment to European integration and its shared identity within the union. The coin was issued as a standard circulation piece to mark this significant milestone in the history of European cooperation. A total of 346,500 coins were minted in 2015.
