Denier - Sobon

Vienne's archbishops gained the right to strike coin through a series of royal concessions extending back to the Carolingian period, but the precise grant underpinning this issue remains disputed among French feudal numismatists — hence the absent PA reference number. The archbishopric sat at a commercially active crossing of the Rhône, giving its deniers genuine circulation weight in the region's trade networks rather than purely ceremonial relevance.

Boudeau 1040 is among the scarcer attributions in the Vienne series.
