Tetrobol "light drachm" A / Π

Massalia — the Greek colony at modern Marseille — maintained remarkable monetary independence long after Rome had absorbed most of Gaul's neighbors. The A/Π designation marks a specific magistrate's control series, one of several overlapping alphabetic sequences the city used to organize production accountability rather than public attribution. The colony continued striking its own silver into the first century BC despite tightening Roman commercial dominance, a privilege Rome occasionally tolerated in loyal client cities.
