A Fatimid-period disk weight, equivalent in weight to two dinars and made of honey-green glass, was found in the northern part of Building III. It bears a three-line stamp of Imām az-Zāhir, the seventh Fātīmid Imām. Similar glass weights are known from Egypt, but have also been found in Syria and Palestine. Some scholars have suggested that these are glass jetons, used as coins. A more widely accepted suggestion is that these are simply dinar and dirham weights.
