1 Sol, 6 Deniers

Geneva struck billon coinage under its own cantonal authority until the Federal Coinage Act of 1850 forced Swiss cantons to surrender monetary independence to the newly centralized Confederation. The 1825 issue came during the final quarter-century of that autonomy, a period when Geneva's coinage was already an anachronism — the city had been absorbed into France in 1798, used French decimal currency for over a decade, and only resumed cantonal issues after Napoleon's defeat. The sol-and-denier system it returned to was feudal in origin, stubbornly pre-metric.
