Swiss 1900 Paris Exposition 5 Francs

This Swiss coin was struck in 900 fine gold to commemorate Switzerland's participation in the 1900 Paris Exposition, a bold move to flaunt the nation's precision in metallurgy amid a sea of international rivals.

That purity level wasn't just for show; it ensured the coin could withstand the pockets of fairgoers who might have mistaken it for a souvenir rather than currency. The obverse bore the Swiss coat of arms, encircled by the inscription "Exposition Universelle Paris 1900," while the reverse depicted a Swiss cross with alpine motifs—simple, effective design choices for an event packed with novelties.

Exact mintage figures? They're murky, lost in the archives of the Swiss National Bank, which isn't unusual for exposition pieces. Some variants exist in silver, but those are scarcer and often debated among us old hands.

And if you think it's just another expo token, well, let's not kid ourselves: it's not.
