20 Francs Jass

Switzerland's Jass card game has been played in its recognizable form since at least the late 18th century, introduced via Swiss mercenary soldiers who encountered similar trick-taking games during foreign service. It remains the country's dominant card game today, with regional rule variants sharp enough to cause genuine disputes across cantonal lines. Swissmint's commemorative series celebrating Swiss cultural traditions has leaned heavily on this kind of deep vernacular heritage — things practiced at kitchen tables rather than displayed in museums.

KM#152 is part of that ongoing cultural series. The .835 silver alloy is the traditional Swiss commemorative standard, unchanged since the mid-20th century.
