Hemiobol

Phokis struck federal coinage in the years immediately before and during the Persian invasions, making this issue contemporary with Thermopylae — a battle fought on Phokian soil after the Phokians themselves had refused to medahize. Their resistance was not universal: the oracle at Delphi, situated in Phokis, had given famously ambiguous counsel to the Greeks, and the sanctuary's enormous treasury made it a primary Persian target in 480 BC.

The BCD reference places this among the earliest federal coinage issues from the region, before the Persian sack disrupted production entirely.
