Tremissis - Marcian VICTORIA AVGVSTORVM, Constantinopolis

Marcian came to power in 450 through a marriage of political convenience to Pulcheria, sister of the recently deceased Theodosius II, bypassing the more obvious succession to legitimize a military man's rule. His reign saw the Eastern Empire refuse tribute payments to Attila — a decision that would have been unthinkable under his predecessor — and the finances stabilized accordingly. The tremissis denomination, a third-solidus, was the workhorse of late antique long-distance trade, particularly along eastern Mediterranean routes.

RIC X 519 is well-documented within the Constantinople mint sequence for this reign.
