1 Koruna Trial Strike

The Czechoslovak koruna coinage program of the early 1920s involved extensive experimental striking before final designs and metals were approved — this gold trial piece at 23.19g represents a test well outside any practical circulation specification, suggesting it was produced for presentation or formal approval purposes rather than as a genuine denomination proposal. The newly independent state, founded only in 1918, was still negotiating the physical parameters of its currency identity when this piece was struck.
