Swiss 50 Francs Bimetallic

This coin's most striking feature is its experimental bimetallic structure, with a brass ring encircling a cupro-nickel center, which helped Switzerland test durability and security in circulation during the late 1980s. That setup was innovative for a nation known for precision engineering, even in its currency. The 1987 issue marked an early adoption of bimetallic technology, predating widespread use in other countries.

Details on production are sparse; records suggest it was struck at the Bern mint, but exact figures remain uncertain due to archival gaps from that era. What we do know is that the design featured the Swiss coat of arms on one side and a landscape on the other, emphasizing national identity without fuss.

Some collectors debate its rarity, though that's likely overstated. As for the bimetallic aspect, it did reduce counterfeiting risks—clever, if you think about it.
