A stray surface find in excavations at Corinth of an Abbasid coin, clipped into the shape of an octagon, presents a puzzle, both methodologically and historically. The possible date and manner of its arrival in the city are studied and the reasons and context of its clipping are considered. A link with octagonal specimens from Trebizond and Antioch-on-the-Orontes is suggested. Another stray find, this time a Chinese coin, also from Corinth, is studied here for comparison.
