The ⅙ stater coin is a circulation coin that was issued around 413 to 406 BC by Akragas (Agrigentum), a Greek city-state located in what is now Agrigento, Sicily. Circulated under the leadership of Magistrate Silanos, the piece was made when Akragas was under threat from Carthaginian invasion during the Second Sicilian War (410 BC–340 BC). It had a value equivalent to ⅙ of a stater, or 2 oboloi/litrae, prior to its eventual demonetization.
The coin is composed of gold and has a mass of approximately 1.32 grams and a diameter of roughly 12 millimeters. It is irregularly round in shape and has a plain edge and varying die axes. Featured on the obverse is an illustration of an eagle facing left or right, perched on a pile of rocks and devouring a snake. Printed above this depiction, near the rim of the coin, is the Greek "ΑΚΡΑ" (Romanized: Akra), an abbreviation for Ἀκράγας ("Akragas"). Also, two pellets are usually displayed below the image of the eagle, representing the coin's value of two oboloi/litrae. A crab is displayed at the top center of the reverse. Inscribed below it is "ΣΙΛΑΝΟΣ" (Silanos), the Greek name of the magistrate, generally separated onto two lines between the alpha (Α) and nu (Ν).
The mintage of the ⅙ stater of Akragas is currently unknown. As rare as pieces with left-facing eagles are, those with right-facing eagles are much more scarce, as only about three are known.
