The owl was the sacred bird of the goddess Athena and the symbol of Athens. From the end of the sixth century BC, it is depicted on the back of the silver Athenian tetradrachm, the famous glaukes (after glaux, the ancient Greek word for owl), the strongest currency of classical antiquity. This tetradrachm shows the owl framed by an olive branch, Athena's sacred plant, a crescent moon on the left and the inscription ΑΘΕ, meaning Athenians, on the right. The coin was found in the archaeological excavation of the Makrigiannis plot, the Acropolis Museum's construction site, and dates to the end of the fifth to the first half of the fourth century BC. This pure silver reproduction of the Museum tetradrachm is cut by The National Mint of Greece for the Acropolis Museum. It is provided to you with the Mint’s Certificate of Authenticity and a brief history of the tetradrachm.
