Denier - Duke Leopold VI Vienna

Leopold VI ruled the Duchy of Austria and Styria simultaneously from 1194, consolidating Habsburg predecessor territory at a moment when Alpine trade routes were generating enough commercial traffic to demand a reliable local silver coinage. The Vienna mint's output under his long reign became sufficiently standardized that these deniers circulated well beyond ducal borders into Bohemian and Hungarian markets.

CNA B101 is among the better-documented types of the Austrian bracteate-adjacent series — thin, broad flans prone to edge splits, which accounts for the relative difficulty of finding intact examples today.
