20 Halierov

Slovakia's wartime bronze issues, including this 20 halierov, were produced under the cleric-nationalist regime of Jozef Tiso — a nominally independent state operating in near-total subordination to Nazi Germany. The National Bank of Slovakia was established only in April 1939, weeks after the rump state's declaration, making these early coinage issues part of a rushed effort to build the material infrastructure of a new country whose sovereignty was circumscribed from the start.

Production ran across three years before wartime metal pressures began reshaping the denomination structure entirely.
