1948 Belgium 10 Francs

The 1948 Belgian 10 Francs coin was issued to commemorate the wedding of Princess Lilian to King Leopold III, though records are murky on whether it was an official endorsement or just timely flattery.

Weighing in at 6 grams of aluminum-bronze, it features Leopold's profile on the obverse, a design choice that reflected the monarchy's attempt to stabilize the nation post-war.

Mintage figures? Lost to history, likely in one of those bureaucratic fires that numismatists love to blame.

The reverse shows the Belgian coat of arms, encircled by the denomination and date, a straightforward layout that collectors appreciate for its lack of frills.

Some say it hints at the era's tensions; others just pocket it quietly.
