Czechoslovakia experimented extensively with coinage alloys during the early 1930s as the Depression eroded the economics of maintaining zinc and cupro-nickel in circulation. This piece is a trial strike — produced not for release but to test the behavior of the brass composition under die pressure and to assess wear characteristics before any production commitment was made. The 1931 date places it squarely in that period of internal review, though the circulating 20 haléřů ultimately retained a different alloy specification.
