Denarius - Ptolemy Caesarea

Ptolemy of Mauretania was the son of Juba II and Cleopatra Selene II — herself the daughter of Antony and Cleopatra — making him the last ruling descendant of both the Ptolemaic and Seleucid lines. His kingdom operated as a client state under Augustus and Tiberius, issuing coins in Roman denominations as a deliberate alignment with imperial currency practice. Caligula had him summoned to Rome and executed in 40 AD, allegedly over a jealous dispute about a purple cloak, extinguishing the dynasty and prompting Rome to annex Mauretania directly.
