Chach — the region around modern Tashkent — operated as a loose constellation of semi-independent principalities during this period, each issuing bronze coinage that circulated within narrow local boundaries. The "flat hair" designation distinguishes this type from related issues by die characteristic rather than by ruler, reflecting how incompletely the Chach series is understood: many rulers remain anonymous, their sequence reconstructed from hoard stratigraphy rather than written records. Shagalov and Kuznetsov's classification system remains the primary framework, though attributions within it continue to be revised.
