Hemiobol

Kyme was among the oldest Greek settlements on the Aeolian coast, but its hemiobol represents a denomination so fractional that its primary function was almost certainly small-scale retail in local markets — fish, oil, a handful of grain. At 0.27g, these pieces were struck with considerable technical difficulty, and surviving examples frequently show off-center dies or incomplete flans, not from carelessness but from the sheer challenge of controlling such a small slug of silver at the anvil.
