Fals - Al-Mutawakkil Sarafaddin Yahya

Al-Mutawakkil Sarafaddin Yahya ibn Yahya was the Zaydi imam who reestablished Rassid authority in Yemen after a prolonged period of fragmentation, ruling from Sana'a during one of the dynasty's more stable intervals. Zaydi copper fals of this period were struck in limited quantities and circulated within tight regional economies — highland Yemeni markets with minimal integration into the broader Abbasid monetary sphere. Most have survived in poor condition precisely because they did circulate, hard.
