This much gold would have been an impressive haul even back then.
Dr Kool said the coins could afford their owner a luxurious house in one of Egypt’s best neighbourhoods, Fustat.
The archaeologist added: “This rare treasure will certainly be a major contribution to research, as finds from the Abbasid period in Israel are relatively few.”
Today, 845 grams of pure gold would be worth nearly £37,000, according to BullionByPost data on January 25 – and that does not include the coins’ historical value.
Hidden among the Abbasid gold was an even rarer treasure – gold cuttings of a Byzantine-era coin bearing the face of emperor Theophilos (829 to 842 AD).
The coin was minted in the Byzantine empire’s capital of Constantinople.
