In this episode, we explore a breathtaking find off Italy’s coast — a buried Roman fortune hidden beneath sea sand for centuries. An amateur diver near Arzachena in Sardinia uncovered between 30,000 and 50,000 fourth-century bronze coins scattered across the seabed, along with amphora fragments from Africa and Asia. Archaeologists say this is one of the most important coin discoveries in recent years, offering a glimpse into Roman trade routes, politics, and economy. The find reveals how currency circulated across the empire, carrying the marks of rulers and mint workshops, and how even small coins can rewrite the story of power, trade, and daily life in the ancient Roman world.
