|The Year Set consists of: 1, 2, 5, 10, 20, 50 cent coins and 1, 2 euros commemorating the 100 anniversary of the death of Grand Duke William IV
The coin commemorates the 100 anniversary of the death of Grand Duke William IV (22 April 1852 - 25 February 1912), who reigned as the sovereign Grand Duke of Luxembourg from 17 November 1905 until his death. He succeeded his father, Adolphe, Grand Duke of Luxembourg. He also held the titular title of Duke of Nassau. William IV was a Protestant, the religion of the House of Nassau. He married Marie Anne of Portugal, believing that a Roman Catholic country ought to have a Roman Catholic monarch. Thus since William IV all other Grand Dukes have been Catholic.
Luxembourg euro coins feature three different designs, though they all contain the portrait or effigy of Grand Duke Henri of Luxembourg. The Grand Duke Henri of Luxembourg appears on the coins facing to the left. Jean's portrait on the francs showed him facing to the right and it is common in a number of countries for successive monarchs to alternate the direction they faced on coins.
