50 Korun Karlovy Vary

Issued to mark the 225th anniversary of the Karlovy Vary spa town's formal recognition, this coin belongs to a late-communist and immediate post-revolution transitional series that Czechoslovakia continued producing almost without interruption through the political upheaval of 1989–1991. The socialist-era commemorative program had long used silver issues as a soft-currency export earner, sold to Western collectors for hard currency — a practice that continued even as the federal state itself was quietly dissolving toward the 1993 partition.

The .700 fineness was a deliberate cost-reduction from earlier Czechoslovak silver issues, adopted in the 1980s and retained through the final federal emissions.
