1 Ducat - Vladislav I Type IIIb1

Vladislav I — known as Vlaicu Vodă — issued these small silver ducats as Wallachia began asserting itself as a distinct political entity between the Hungarian kingdom to the north and the Bulgarian tsarates to the south. The denomination itself borrowed the "ducat" name from Venetian and Hungarian currency, reflecting the trade networks these coins were meant to facilitate rather than any direct monetary alignment with those powers.

The MBR classification splits this type across three reference numbers, indicating die variation significant enough for specialists to distinguish subgroups within what was already a short production window tied to a single reign.
