Two Israeli teenagers on summer break unearthed a trove of hundreds of gold coins that date from 1,100 years ago.
     The hoard, buried in a clay jar, was discovered at an archaeological dig in Yavne in central Israel, said the Israel Antiquities Authority (IAA) on Monday.
     Robert Kool, a coin expert with the IAA, said the coins date back to the end of the 9th century when the region was under the control of the Islamic Abbasid Caliphate, a dynasty which ruled a territory from modern-day Algeria to Afghanistan. The coins -- 425 in all -- were made of pure 24-karat gold and weighed 845 grams (1.86 pounds).
     "With such a sum, a person could buy a luxurious house in one of the best neighborhoods in Fustat, the enormous wealthy capital of Egypt in those days," said Kool.The teenagers, who were taking part in pre-military national service, initially thought they had found some very thin leaves buried in a jar.
     "It was amazing. I dug in the ground and when I excavated the soil, saw what looked like very thin leaves," Oz Cohen, one of the youths who found the coins, said in a statement.

     "When I looked again I saw these were gold coins. It was really exciting to find such a special and ancient treasure."
     Finding such a large cache of gold coins is exceedingly rare, said the directors of the excavation site, since gold was often melted down and reused by later civilizations.

     "The coins, made of pure gold that does not oxidize in air, were found in excellent condition, as if buried the day before. Their finding may indicate that international trade took place between the area's residents and remote areas," said Liat Nadav-Ziv and Elie Haddad from the IAA.
