Tetradrachm- Cleopatra III and Ptolemy X

Cleopatra III was the dominant political force in this joint reign — she had already co-ruled with one son (Ptolemy IX) before engineering his expulsion from Egypt in 107 BC and replacing him with her younger, more malleable son Ptolemy X Alexander I. Ancient sources, particularly Justin, portray her as unusually aggressive in wielding maternal authority over the throne. The coins of this brief co-regency reflect that political instability; the pairing lasted only two years before the dynastic maneuvering resumed.

Struck at Alexandria. The series is catalogued under Svoronos 1728 with limited die variation documented.
