This 5 Francs silver coin was issued by the Kingdom of Belgium in 1850 under King Leopold I (KM# 17). The obverse features a left‑facing portrait of Leopold I with the French legend “LEOPOLD PREMIER ROI DES BELGES” and the engraver’s name “L. WIENER” below the bust. The reverse shows the Belgian crowned coat of arms with the rampant lion on a shield, flanked by the denomination “5 F,” surrounded by a laurel wreath and the national motto “L’UNION FAIT LA FORCE” above, with the date 1850 below.
