50 Korun Český Krumlov

Český Krumlov entered UNESCO's list of protected historic sites in 1992, but Czechoslovak cultural authorities were promoting the town's Gothic and Baroque architectural complex well before that recognition arrived. This coin was part of a long-running socialist-era commemorative program that used silver issues to assert national cultural heritage — a policy with the secondary effect of generating hard currency through collector sales abroad.

The .500 fineness is characteristic of the entire Czechoslovak commemorative silver series from this period, a deliberate economy that kept bullion costs manageable while retaining the prestige of a silver designation.
