20 Francs Max Frisch, trial

Trial pieces from Swissmint's commemorative program rarely surface in trade — they exist to test die alignment, edge tooling, and planchet behavior before authorized mintage begins, and most are destroyed or retained internally. This example honors Max Frisch, the Zurich-born novelist and playwright whose Homo Faber and Stiller earned him a place among the defining German-language writers of the postwar decades. The 2011 issue marked the centenary of his birth.

The HMZ and Richt references confirm trial status, distinguishing it sharply from the circulating commemorative.
