The Vandals, after capturing France and Spain, invaded and conquered North Africa in 429 AD. Justinian completed his reconquest of the province from the Vandals in 535 AD, though minor mopping up operations against the Moors lasted until 548 AD. It is recorded that the reconquest cost 100,000 pounds of gold. This extraordinary solidus naming Alexandria in the exergue tells the world that the Romans had retaken Alexandria, thus Egypt and North Africa.
