1 Fals - 'Ala al-Dawla Yazd

The Atabegs of Yazd were a minor dynasty that managed to survive well into the Ilkhanid period by accepting Mongol suzerainty — a political accommodation that kept local coinage in production long after neighboring dynasties had been absorbed entirely. By 1285, 'Ala al-Dawla was operating firmly within that tributary arrangement. The denomination name "Fals" typically implies copper, making a silver flan for this type either a deliberate departure or a classification anomaly worth noting against Album 1933.
