Earlier Roman gold coins (aureus?) apparently were not minted in high quantity. BUT from the reign of Arcadius or Theodosius II in the Eastern Roman Empire (or Byzantine) gold coins were struck in large quantity. Haven't you noticed that not many Roman gold coins are listed for bidding, while that number soars from the reign of Theodosius II and onwards?? In Vcoins if you seach after "Aureus" then only 133 items appear. But for "Solidus" the number is 511 items. (for the record: the number will soar if we include "Histamenon" and "hyperpyron") Gold coins of Thedosius II, Justinian, Heraclius, Constans II, Basil the Macedonian, Constantine VII, Romanus III, Alexious Comnenus, John II Comnenus and Andronicus II are the most common. So, can anybody tell me what happened in the reign of Arcadius/Theodoius II? What is the explanation?
