20 Euro Cents - Guillaume V

Luxembourg's coinage shifted to Grand Duke Guillaume V following the abdication of Henri in October 2024 — the first abdication in the country's modern history. Henri cited age and a desire for generational transition, making Guillaume, at 42, the youngest reigning Grand Duke in decades. Coins bearing Guillaume's effigy began entering circulation with the 2025 issues; the 2026 date places this piece in the early, still-limited run of his reign.
