This article intends to appraise differences in monetization of urban and rural contexts in the Celtic world, on the basis of the distribution of the means of producing coinage. Various sets of archaeological evidence, amongst which eighty-three monetary dies and twenty-eight punches, allow to identify about fifteen Celtic mints, mainly on oppida, but also in rural settlements, as well as some itinerant craftsmen. The case of the Vindelici, a federation of tribes in the south of Bavaria, where archaeological traces of five workshops were discovered, show the decentralization of monetary production, from the oppida to the countryside, but the lack of precision of the available chronology does not permit to date this decentralization more accurately than between the middle of the second and the middle of the first century BC, and thence to discover whether this decentralization was contemporary of the peak of the oppida or rather was a result of their decline starting in the years 80 BC.
