Comment

Known as 'Gehelmde Groot' or 'Herengroot' (Dutch).

William acceded to the throne of Guelders in 1371 at the age of 7, and reached his full majority in 1377.

When his father, William II Duke of Julich, died in 1393, the crowns of Guelders and Julich became united in a personal union under WIllem (who was WIlliam III of Julich). This coin is from the part of his reign before this union, and has been estimated to have been issued about 1390.
