Paika - Mu'izz Al-Din Kaiqubad

Kaiqubad's reign lasted barely three years before he was murdered on the orders of the Khalji chief Jalal ud-Din Firuz, who then founded the Khalji dynasty in 1290. The paika — the smallest copper unit in the Delhi Sultanate's currency hierarchy — circulated almost exclusively at the local bazaar level, handling transactions too small for silver. Kaiqubad himself was reportedly incapacitated by a stroke midway through his reign, leaving real power with court factions, which may partly explain the administrative inconsistency seen across his copper issues.
