Tetradrachm - Ptolemy VI Philometor Alexandria

Ptolemy VI Philometor ruled under one of the most chaotic regencies in Ptolemaic history — his mother Cleopatra I held effective power until her death in 176 BC, after which two incompetent ministers drove Egypt into a disastrous war with Seleucid Syria. Antiochus IV invaded twice, and for a period Egypt held the unprecedented situation of three co-rulers simultaneously: Ptolemy VI, his brother Ptolemy VIII, and their sister Cleopatra II. Rome's intervention in 168 BC — a single envoy drawing a circle in the sand around Antiochus and demanding he withdraw before stepping out — ended the crisis without a battle.

The Alexandria mint maintained the closed currency system that had defined Ptolemaic Egypt since the third century, forcing all foreign silver to be reminted at a loss to the holder. Svoronos 1446 falls within the later portion of Philometor's personal reign, after he consolidated sole rule in 163 BC.
