The Principality of Chach occupied the Tashkent oasis in what is now Uzbekistan, a zone that changed hands repeatedly between Sogdian, Turkic, and eventually Arab authority across the seventh and eighth centuries. Coins from this period and region were struck under a loosely defined succession of local rulers whose names and precise reigns remain poorly documented — hence the anonymous attribution. Sh&K 255 sits within a classification system that is itself still being refined as Central Asian numismatics catches up to the archaeological record.
