Byzantine Polyhedron Weight Standard. Ca. 400–700 AD. Bronze, 17.8 mm, 16.2 g. Byzantine bronze commercial weights reflect the highly regulated economy of the early empire. Based on Roman libra and uncia standards, they were used to verify quantities in markets, workshops and official transactions. Crosses, Greek numerals and occasional silver inlay identified denominations and reinforced imperial authority, offering direct evidence for everyday trade, taxation and administration.
