200 Korun Accession to the European Union

The Czech Republic's accession on May 1, 2004 came as part of the largest single enlargement in EU history, when ten countries joined simultaneously. Prague had pushed hard for membership since the mid-1990s, though domestic enthusiasm was notably cooler than in some neighboring states — Czech euroscepticism ran deep enough that the country would remain outside the Eurozone indefinitely, a position that has never substantively changed.

The .900 fineness used here was already being phased out in favor of .925 for subsequent Czech commemorative issues.
