Æ Fals Kayqubad I bin

Kayqubad I — Ala ad-Din Kayqubad — ruled the Seljuk Sultanate of Rûm at its political and cultural peak, pushing territory to the Mediterranean coast and briefly controlling Crimean trade routes after taking Sudak in 1225. His copper fals coinage circulated in a local economy where silver dirhams handled long-distance trade; fals like this one were the working currency of bazaars and small transactions throughout Anatolia. The type spans nearly two decades of his reign, making precise dating within that window impossible without die study.
