Athenian Tetradrachm

The Athenian Tetradrachm's owl reverse, symbolizing Athena, turned it into a de facto international currency across the Mediterranean for centuries.

Struck in Athens from silver mined at Laurium, these coins featured Athena's helmeted head on the obverse and the owl with an olive sprig on the reverse—a design that remained consistent from around 510 BCE until the late 5th century BCE. We don't know the exact mintage figures; records from that era are scarce, lost to time and the elements. What we do have are thousands of surviving examples, dug up from shipwrecks and hoards, showing wear from heavy circulation.

Imitations popped up everywhere, from Egypt to Sicily, as Athens dominated trade. People still peddle myths about these coins bringing wisdom or luck, but after thirty years, I've seen enough fakes to know it's just silver and history. No magic involved.
