1/3 Tanka - Hasan 'Ali

Historical Context: This 1/3 Tanka of Hasan 'Ali (AH 872-873 / 1467-1468 CE) emerges from the final, tumultuous period of the Qara Qoyunlu (Black Sheep Turkomans) tribal federation. Hasan 'Ali, the last effective ruler, faced relentless pressure from the ascendant Aq Qoyunlu under Uzun Hasan, coupled with internal dissent. Issuance of coinage, even fractional denominations, during this terminal phase reflects a desperate attempt to assert sovereignty and maintain administrative function amidst the rapid disintegration of his realm, which ultimately collapsed with his defeat and death in 1468.

Artistry: The artistic style is characteristic of contemporary Islamic numismatics, heavily reliant on epigraphy. Individual engraver signatures are virtually unknown for Qara Qoyunlu issues, particularly fractional types. The aesthetic focus lies entirely on the calligraphic rendering of religious formulae, such as the Kalima, and the ruler's name and titles, often accompanied by the mint and date. While influenced by broader Ilkhanid and Timurid traditions, the execution often exhibits a more localized, sometimes less refined, character typical of tribal confederation coinage.

Technical/Grading: For this type, critical high-points for grading include the clarity and completeness of the central legends on both obverse and reverse, which often feature the ruler's name and titles. Given the irregular planchets and frequently weak strikes common to fractional issues of this period, a full and legible rendering of the mint and date, typically found in the marginal legends, significantly enhances value. A well-centered strike, even if light, that preserves all critical inscriptions is highly desirable.
