TWO rare gold coins from the reign of Emperor Valens have been unearthed in Egypt. Nevine El-Aref reports on the find. Archaeologists from the Supreme Council of Antiquities (SCA) carrying out a routine archaeological survey at Sail Al-Tofaha area, west of Saint Catherine's Monastery in Sinai, have chanced upon two gold Byzantine coins bearing the head of Emperor Valens (364-378 AD). A number of grotto caves and fragments of clay and glass have already been found in the area.
