1 Koruna Trial Strike

Czechoslovakia's postwar coinage program moved slowly after the state's 1918 declaration of independence, with definitive circulation types not fully established until the mid-1920s. Trial strikes in gold were produced during the design evaluation phase — not as proofs intended for collectors, but as working tests to assess die quality, relief depth, and strike pressure before committing to base-metal production runs. The 1922 date places this piece squarely in that developmental window, before the standard cupronickel koruna was regularized for circulation.
