Medieval silver coin. This coin, which dates from the early Middle Ages (approximately the 5th-10th centuries AD), was discovered during excavations at the Abbey of San Vincenzo (Saint Vincent), at Isernia, north of Naples, Italy. The abbey, founded in 703 AD on the ruins of a 5th century Roman oratory, was burnt to the ground by the Saracens in 881 AD, and then rebuilt from 914 AD. In the 12th century, the abbey was moved a short distance away to a new location. The original abbey site was most recently excavated in the period 1999-2003.
