Belgium 100 Francs

This Belgian 100 Francs coin, struck in .925 fine silver for proof sets between 1975 and 1980, was notable for its use of recycled silver from outdated currency stocks, a practical nod to postwar frugality.

Designs varied by year, often featuring royal portraits or national symbols like the lion rampant, engraved by artists such as Lucien De Greef. Not every year saw a release; records from the Brussels Mint are spotty, with some dates possibly unissued. I've turned a few over in my hands over the decades, always appreciating the crisp edges and mirror finish that set proofs apart.

Mintage figures? They're as elusive as a quiet day at a coin show. Estimates float around tens of thousands per year, but I'd rather not guess.

Some collectors swear by its investment potential; I've sold enough to know it's steady, if not spectacular.
