The 2018 Luxembourg 2 euro commemorative coin honours Grand Duke Guillaume I, marking the 175th anniversary of his death. The national side features a profile portrait of the Grand Duke, who served as the first sovereign of the Grand Duchy of Luxembourg after the country gained its independence in 1839. His leadership was pivotal during the early years of the nation’s formation, establishing the foundations of the Luxembourgish state. The design captures the historical significance of his reign, reflecting the constitutional transition that defined the country's modern identity. Surrounding the portrait are the name of the monarch and the commemorative dates, symbolising the enduring legacy of the House of Orange-Nassau in Luxembourgish history. This coin was issued in 2018 with a mintage of 300,000 pieces.
