A solidus of Justinian I from the Constantinople mint, 538–545 AD. A specimen recorded at Dumbarton Oaks has an actual weight of 4.39 grams of gold and a diameter of 20 mm. It features a large, front-facing bust of the emperor. The circulation area of the solidus-nomisma, traced through coin finds, extended from England to India, and it remained the monetary standard of the Mediterranean world. This is a coin from an emperor who was central to the seven centuries during which its fineness was maintained.
