The 2020 Greece 2 euro commemorative coin marks the centenary of the Union of Thrace with Greece, a pivotal moment in the nation's modern territorial formation. The design features a depiction of a coin from the ancient city of Maroneia, specifically a drachma showing a prancing horse. This historical motif serves as a symbol of the region's deep-rooted Hellenic identity and its long-standing cultural heritage. By incorporating this ancient imagery, the coin commemorates the 1920 incorporation of Western Thrace into the Greek state, an event that reshaped the country’s northern borders following the First World War. This issue was released in standard circulation format with a total mintage of 743,000 coins in 2020.
