50 Euro

The 2017 Belgian 50 Euro gold coin was struck using 999.9 fine gold, a purity level that makes it one of the few Euro issues designed for investment rather than circulation.

That decision reflected Belgium's tradition of producing high-quality commemoratives, often tied to national milestones. For this piece, the design likely drew from historical themes, though exact inspirations remain murky in mint records. We know it featured the standard Euro obverse with the country's emblem, but specifics on the reverse—possibly a cultural motif—weren't always documented well.

One detail that's clear: the coin's edge is reeded, a practical choice to deter counterfeiting. As for its rarity, production figures are uncertain, lost perhaps in the Royal Mint's archives.

Collectors sometimes overstate its scarcity, which gets old after a while.
