When did a solidus coin become a bezant?
Excuse me, could you clarify for me when exactly did the solidus coin evolve into what we now know as a bezant? I'm curious about the historical timeline and the specific events that led to this transition. Was it a gradual process or was there a definitive moment when the solidus ceased to be and the bezant emerged? I'm eager to understand the context and significance of this change within the broader history of currency and trade.
