⅙ Assis

Zug was among the smallest and least economically active of the Swiss cantons, and its billon fractional issues of this period were struck in quantities so modest that they rarely traveled far from local markets. The denomination itself — one-sixth of an assis — reflects a monetary subdivision so small it had almost no practical utility beyond petty market transactions, yet the canton maintained the issue across five decades, suggesting a persistent local demand that larger denominations couldn't satisfy.
