Æ19 - Antoninus Pius L ΕΝΑΤΟΥ

The regnal year designation L ΕΝΑΤΟΥ — "year nine" — places this issue squarely in 145/146 AD, during a period when Alexandrian civic bronze was being struck in unusually high volumes to support the grain economy of Roman Egypt. The prefecture's mint operated under tight imperial oversight; local bronzes circulated almost exclusively within Egypt, functioning as a closed currency system that never left the province.
