A medal bearing the name "Olympias" was found in 1902 at Abu Qir, Egypt that dates back to AD 225-250, and belongs to the Archaeological Museum of Thessaloniki. The reverse shows a Nereid mounted on a fantastic sea creature. It had been suggested that the Olympias depicted on the medal was Queen Olympias, but this theory has been challenged. The name ΟΛΥΜΠΙΑΔΟΣ is thought to refer to the Olympiads instead.
