AR25 - Nero ΔΙΚΑΙΟΣΥΝΗ, L Γ

Alexandria's mint operated under tight imperial oversight, and this third-year issue falls within Nero's early reign when his administration was still shaped heavily by Burrus and Seneca — a period later ancient sources would call a kind of golden quinquennium. Egyptian provincial coinage ran on a closed currency system: Roman denarii could not circulate freely in Egypt, forcing all transactions through locally produced billon tetradrachms controlled entirely by the prefect's office.

The billon content at this stage had not yet suffered the aggressive debasement Nero would impose later in his reign, making L Γ issues measurably more silver-rich than their successors from years five onward.
