Swiss 10 Rappen Aluminum

Switzerland's 10 Rappen coin switched to aluminum in 1940, a direct response to wartime shortages that forced the country to repurpose metals for essential uses. This meant scrapping the usual copper-nickel alloy in favor of a lighter, more abundant material sourced from domestic supplies.

The design remained straightforward: a simple Swiss cross on the obverse, with the denomination and year on the reverse. No fancy flourishes; it was a practical piece for a neutral nation navigating global conflict. These coins circulated widely during the war years, from 1940 through 1945, as Switzerland maintained its economy amid external pressures.

Exact mintage figures are murky—records from that era weren't always meticulous. What we do know is that production peaked early in the decade, tapering off as conditions eased.

Aluminum coins like this one often show wear quickly, a reminder that necessity isn't always kind to currency.
