1/2 Ducat - Georg III, Ludwig IV and Christian

Georg III, Ludwig IV, and Christian ruled Liegnitz-Brieg jointly as the last male line of the Silesian Piasts — a dynasty that had governed parts of Silesia since the 13th century. The duchy's days were numbered; when Christian died without male heirs in 1672, the Habsburgs absorbed the territory under the terms of a 1537 succession treaty that the Silesian dukes had spent generations trying to circumvent. These joint-reign issues of the early 1650s were struck in the shadow of that legal vulnerability, with the three brothers well aware that imperial pressure on their inheritance was mounting.

Liegnitz-Brieg ducats from this period were produced in small quantities, and the half-ducat denomination is considerably scarcer than the full ducat across all surviving examples.
