People used coin weights such as this in Egypt under the Fatimid dynasty (969-1171). This example weighs 1.00 grammes and we think it was used to balance gold coinage weighing one quarter of a dinar. It was produced in the reign of the last Fatimid caliph, al-'Adid (ruled 1160-1171). His full regnal name, al-'Adid li-Din Allah, appears between the titles Imam and Commander of the Faithful on the obverse. (This is the side of the coin that carries the main design.) The reverse is blank.
