1964 Belgium 20 Francs Olympic Games

This 1964 Belgian 20 Francs coin features a design by Marcel Rau that integrates the Olympic rings with a stylized athlete, a nod to the Tokyo Games despite Belgium's athletes securing only a handful of medals.

Struck in .835 fine silver, it weighs 10 grams and measures 27 mm across. The edge bears the inscription "BON POUR" followed by the denomination, a practical detail from Belgium's coinage traditions. I've examined dozens of these over the years, and they're often in decent condition, though edge wear is common from pocket storage.

Mintage records are murky; estimates float around 500,000, but I wouldn't bet on it. Some say a fire at the Brussels mint archives in the 1970s wiped out precise figures.

It's amusing how collectors hype these as rare, when in reality, they're as common as rain in Flanders.
