The Monaco 2012 2 euro commemorative coin honours the 500th anniversary of the sovereignty of the Principality. The national side features a portrait of Lucien I Grimaldi, who served as the Lord of Monaco from 1505 to 1523. His leadership was pivotal in securing the independence of the territory, a milestone that remains central to the national identity of the Grimaldi dynasty. The design includes the name 'LUCIEN I' positioned above the portrait, with the word 'MONACO' inscribed along the upper edge of the inner circle. Flanking the portrait are the years 1512 and 2012, marking the half-millennium of autonomy. This issue was released in standard circulation format with a total mintage of 100,000 coins.
