New Euro Coins Bearing the Effigy of Grand Duke Guillaume 2026 - Grand Duchy of Luxembourg

NEW EURO COINS BEARING THE EFFIGY OF GRAND DUKE GUILLAUME 2026 - GRAND DUCHY OF LUXEMBOURG

NEW LUXEMBOURGISH EURO COINS THE VISUAL OF THE 8 NEW COINS The design of Luxembourgish euro coins changes following the accession to the throne of H.R.H. Grand Duke Guillaume on October 3, 2025. Both the new and old Luxembourgish euro coins are legal tender. The circulation date for the new euro coins is July 13, 2026. As the Grand Duchy of Luxembourg has a new Sovereign, all 1 cent to 2 euro coins minted with the 2026 vintage feature a new design. For each group of coins (1 to 5 cents, 10 to 50 cents, 1 and 2 euros), a new design was created by Ms. Chiara Principe, an artist specializing in the graphic design of circulation and collector coins. The common European side of the coins remains unchanged. (photo – Chiara Principe)
