Unknown Æ - Rast Middle Period

Chorasmia occupied the lower Oxus delta region — modern Uzbekistan and Turkmenistan — and maintained its own coinage tradition largely independent of both Sasanian and Sogdian monetary influence during this period. The "Rast Middle Period" designation follows Vainberg's classification of the local dynastic sequence, a chronology still contested among specialists working from the Zeno corpus and Soviet-era excavation reports. Attribution remains uncertain enough that "Unknown Æ" is the honest call.
