5 Francs - Léopold I

Belgium's early silver 5 franc coinage under Léopold I was struck against a backdrop of ongoing monetary negotiations that would eventually produce the Latin Monetary Union in 1865 — the very year this type ceased production. France, Belgium, Switzerland, and Italy standardized on identical specifications partly because Belgian coins like this one were already circulating freely across borders, creating pressure for formal agreement rather than continued ad hoc acceptance.

Léopold I died in December 1865, making the final-year pieces contemporaneous with both his death and Belgium's entry into the LMU.
