1/2 Ducat - August William

August William ruled Brunswick-Wolfenbüttel from 1714 until his death in 1731, governing a territory whose ducat coinage remained tied to the conventions of the Holy Roman Empire's gold standard throughout his reign. The fractional ducat series was primarily intended for gift-giving and court ceremonial use rather than heavy commercial circulation, which accounts for the relatively high survival rate in presentable condition.

The Welter reference places this squarely within a well-documented Brunswick sequence, though individual die marriages across the 1716–1721 run show enough variation to reward close examination of the reverse field.
