Archaeologists said they have unearthed more than 250 gold coins from the seventh century on the edge of Jerusalem's Old City. A British tourist volunteering at the dig discovered the trove on Sunday. Israel's Antiquities Authority said the Byzantine-period hoard was found in the ruins of a building where a striking 2,000-year-old gold earring from the Roman era was dug up last month. The site is located in a parking lot alongside the city's southern wall. The coins bear the image of the Byzantine emperor Heraclius, who ruled between 610 and 641 AD, depicted wearing military dress and holding a cross in his right hand. A statement Monday said the coins had likely been hidden in a niche in one of the building's walls.
