25 Korun Slovak Uprising

The Slovak National Uprising of August 1944 was the largest armed resistance action in occupied Central Europe during World War II, drawing in tens of thousands of partisans before German forces crushed it within two months. Czechoslovakia commemorated it repeatedly in silver throughout the 1950s, this 1954 issue among them — part of a deliberate postwar policy of anchoring the new communist state's legitimacy to antifascist resistance credentials.

Half-silver at .500 fine, a composition the Czechoslovak mint used consistently for commemoratives of this period rather than the higher fineness of earlier republican issues.
