Denier anonymous with SM

The archbishops of Vienne exercised comital rights over their city from the late tenth century, and the anonymous deniers struck under their authority deliberately avoided episcopal identification — a practice common where temporal and ecclesiastical legitimacy were still being negotiated with the Holy Roman Empire. Vienne sat within a region where imperial, papal, and local interests collided repeatedly in the eleventh and twelfth centuries, and anonymous coinage was as much a political hedge as a monetary one.

The SM monogram references Saint Maurice, patron of the city and its cathedral chapter.
