Hugh Aimeri served as bishop of Saint-Paul-Trois-Châteaux during a period when the small Tricastin diocese, wedged between the Dauphiné and Provence, was asserting its mint rights with unusual persistence for so minor a see. The billon obol represents the fractional end of a coinage whose volume was never large — the diocese lacked the commercial weight to demand heavy circulation, and surviving pieces are correspondingly scarce across all denominations.
Chareyron's regional study remains the primary reference for Tricastin episcopal coinage, with Duplessy's féodales cataloging offering broader context for the type's placement within southern French feudal issues of the 1330s and 1340s.
