1 Koruna Trial Strike

Czechoslovakia's post-independence coinage program was a contested affair. The newly formed republic, established in 1918, spent several years debating compositions, designs, and denominations before settling on a final circulating series. This 1921 copper-nickel trial strike sits in that deliberation period — a test piece produced to evaluate a specific alloy and weight standard that was ultimately not adopted for the circulating 1 koruna.

The production of trial strikes in multiple compositions was standard Czechoslovak mint practice during this window, making attribution sometimes difficult without die-matching to confirmed examples.
