Robert Kool, a coin expert with the antiquities authority, said an initial analysis indicates the coins date from the late 9th century, considered the golden age of the Abbasid Caliphate that controlled most of the Near East and North Africa.

“Hopefully the study of the hoard will tell us more about a period of which we still know very little,” Kool said.
