2 Francs Belgium

The Belgian 2 Francs coin was one of the few silver denominations that circulated seamlessly across borders in the Latin Monetary Union, rubbing shoulders with French and Italian currency as if they were old pals. This made it a practical piece for traders from Brussels to Rome, long before the euro simplified things.

Weighing about 10 grams and measuring 27 millimeters in diameter, it featured the profile of the reigning monarch—Leopold II for most of its run—on the obverse, with the Belgian coat of arms on the reverse. Minted in Brussels, production varied by year, but records from the later 1800s show peaks during economic booms. Not every detail is clear; for instance, exact mintage figures for 1885 were likely lost in administrative shuffles.

If you're hunting for one, expect wear from heavy use; these weren't kept in velvet boxes. Some say they brought good luck, but that's just coin folklore—I've seen enough to know silver tarnishes, not charms.
