1 Ducat - William IV Death

William IV of Orange-Nassau died in October 1751, leaving his three-year-old son William V as heir and his wife Anne of Hanover — daughter of George II — as regent. This ducat was issued to mark his death, a practice common among the smaller German principalities where dynastic events routinely prompted memorial coinages. Nassau-Dietz itself had been the cadet branch responsible for keeping the Orange-Nassau line alive through the Dutch stadtholderless periods.

KM#8 is a scarce type; memorial ducats from minor German courts rarely survived in quantity, as they were often melted or hoarded individually rather than circulating.
