Obole

The Bishops of Geneva exercised temporal coinage rights formally confirmed under the Holy Roman Empire, striking small silver fractions for local market transactions at a time when the city was locked in grinding jurisdictional conflict with the Counts of Savoy. That struggle over Geneva's political allegiance — episcopal independence versus Savoyard annexation — would not resolve for another two centuries, but the mint operated throughout.

At 0.38g, these were the smallest practical silver denomination in circulation, handling transactions too trivial for larger episcopal issues.
