Hoei (Huy, mint in the province of Liège, Belgium, on the Meuse) was a prosperous city from the 7th to the 15th century, notable
for its copper industry. Merovingian monetarii, Carolingians, and German emperors struck coins there, followed by the bishops
of Liège from the late 10th to mid-14th century. During World War I, Hoei issued five series of emergency money, dated 31
August and 6 October 1914, 1 June and 8 December 1915, and 1 August 1916.
