According to Grierson (p.79) the coinage patterns in north and south Italy began to draw apart and by the 11th century two quite distinct systems emerged in southern Italy and Sicily. Byzantine and Arab influence determined the designs, while the bronze coinage was heavily influenced by Byzantine designs. The supply of circulating Byzantine coins provided the metal for production and the overstriking on earlier issues has helped numismatists establish a firm chronology for the coinage.
