Nice example of this SCARCE type minted during the joint reign of Cleopatra and Caesarion son of Julius Caesar. The portrait on the Caesarion types is distinctive vs. the other late Ptolemies with a more rounded and youthful style.
Ptolemy XV was born in 47 BCE and named Caesarion or "the little Caesar". He was son of Julius Caesar by Cleopatra VII. Caesarion reigned from 44 - 30 BCE as a co-regent with his mother until her death in August of 30 BCE. He then served for 11 days as sole ruler until being put to death by Octavian who did not want a challenger to his title.
