9 Deniers / 3 Quarts

Geneva's monetary system in the mid-eighteenth century was a fractional tangle, with the denier, sol, and florin coexisting alongside French and Savoyard currency that circulated freely across the city's borders. The 9 deniers denomination — equivalent to 3 quarts in the local accounting system — addressed the everyday small transactions that larger coins could not efficiently handle in a commercial republic whose banking reputation already far exceeded its physical size.

Billon coinage of this type was notoriously susceptible to debasement pressure during the period, and Geneva's city council repeatedly revisited the alloy specifications across the thirty-two year run of this type.
