Obol

Psophis was a small Arcadian city hemmed in by the Erymanthos river on three sides — geographically isolated enough that its independent coinage output was limited and its issues remain rare today. The city appears in Polybius as a strategically contested point during the Achaean-Macedonian conflicts of the third century, but this obol predates those troubles by two centuries, struck when Psophis held enough commercial independence to mint on its own authority.

The BCD Peloponnesos collection, one of the most exhaustive private assemblings of Peloponnesian coinage ever formed, recorded only a single example at auction in 2004.
