The Central Bank of Luxembourg has presented the new national sides for Luxembourg’s euro coins following Grand Duke Henri’s abdication and the accession of Grand Duke Guillaume on 3 October. Coins bearing the new sovereign’s effigy will be introduced in 2026, while all Luxembourg euro coins issued since 2002 will remain valid legal tender and will not be withdrawn. The bank coordinated the redesign with the Grand Duke’s Household and in collaboration with the Ministry of State and the Ministry of Finance, using specialist artists to translate the portrait into coin-ready designs. For circulation coins, three distinct designs will be used across denomination groups (1, 2 and 5 cents; 10, 20 and 50 cents; 1 and 2 euros), with the monarch depicted facing left in line with the tradition of reversing portrait orientation at a change of reign; all will carry the year “2026” and the designer’s initials “CP” (Chiara Principe). For collector coins issued from 2026, a new obverse design was also selected and validated, featuring a stylised full effigy and the initials “A.H.” (Helmut Andexlinger). On production, the Central Bank of Luxembourg launched a tender in early August 2025 to have the new Luxembourg coins produced from 2026, with the selected mint and the total 2026 mintage not yet determined; it noted that around 9 million coins were struck in 2025. The eight standard denominations from 1 cent to 2 euros will be minted with a 2026 date, and the bank will inform the public and collectors when the new coins are available, including collector issues offered in different striking qualities and sets.
