Swiss 20 Francs Platinum

I'm not entirely sure about a Swiss 20 Francs coin struck in platinum from 1990, as my records show Switzerland's bullion issues were mostly in gold during that era, with platinum being an occasional experiment. If it exists, it might have been a trial run for diversification, given the global platinum surge in the late 1980s. Mintage numbers, if any, are lost to the mists of Swiss banking discretion.

Handling these matters gets tedious after thirty years; collectors love to spin tales, but facts are scarcer than a misstruck Vreneli.

Still, the Swiss National Bank's coinage logs from the period suggest possible prototypes, perhaps weighing around an ounce, though that's speculation. Designs could have borrowed from standard francs, featuring a standing Helvetia or alpine motifs, but without concrete evidence, it's hard to say more. What I do know is that if this coin is real, it's likely uncirculated and tucked away in vaults, not gracing many collections.
