WOW. What are those dimensions? I have a Tetartemorion at 0.15g... Ionia, Kolophon, 6th-century BC AR tetartemorion, 0.15g; 530-520 BC Obv.: Archaic head of Apollo left. Rev.: Incuse punch. Reference: SNG Kayhan 343
@Alegandron It is 5mm in diameter, but I do not have an accurate weight on it yet. It registered as 0.0g on a scale accurate to 0.1g.
