Nummus - Theodosius II cross in wreath, Cyzicus

Theodosius II ruled for over four decades — the longest reign of any emperor in Roman or Byzantine history — yet the tiny bronze nummus occupies the lowest rung of a monetary system badly degraded by the fourth century's repeated currency reforms. By the 420s, the nummus existed largely as a token denomination, its purchasing power so negligible that ancient sources barely bother to record prices in it. RIC X 449 is assigned to the Cyzicus mint, one of the eastern empire's most productive and administratively significant mints, located on the Propontis and closely tied to supply chains for the eastern frontier.
