1 Follis - Sergio I

Historical Context: This 1 Follis coin was issued by Sergio I, the first hereditary Duke of Naples, during his reign from 840 to 864. This period marked a pivotal era for the Duchy, as Naples solidified its independence from the Byzantine Empire. Sergio I navigated complex political alliances and frequent conflicts with Lombard and Saracen forces. The issuance of a distinct ducal coinage under his rule underscored Naples' growing autonomy and its emergence as a significant regional power in Southern Italy.

Artistry: The artistry of this Follis reflects the provincial numismatic style prevalent in early medieval Southern Italy. While no individual engraver is attributable, the design likely emanated from a local mint workshop. It drew inspiration from late Byzantine prototypes but was executed with characteristic simplification and stylization. The obverse typically features a frontal bust, often crude, representing the Duke, while the reverse usually displays a monogram or an inscription. This utilitarian copper coinage prioritized legibility over intricate detail for practical circulation.

Technical/Grading: As a copper follis from the 9th century, this coin often exhibits typical production characteristics. High-points for wear and strike quality include central features of the obverse bust—such as the nose, eyes, and crown—along with core elements of any reverse monogram or legend. Strikes are frequently irregular, leading to off-center designs or incomplete legends. The 7.0 gram weight and 26 millimeter diameter indicate a substantial module, yet variable striking pressure and uneven flans are common, impacting overall preservation and design sharpness.
