Tanka - 'Abd Allah Bahadur Khan II Bukhara

Historical Context: This silver Tanka was issued during the reign of 'Abd Allah Bahadur Khan II (r. 1583-1598), the last great ruler of the Shaybanid dynasty in Bukhara. His era marked the zenith of Shaybanid power, characterized by significant territorial expansion, consolidation of control over Transoxiana, and a flourishing of arts and sciences in Bukhara, which served as a major cultural and economic hub. The Tanka was a prominent silver denomination, facilitating trade and reflecting the economic stability of the Khanate during this prosperous period.

Artistry: Shaybanid coinage, including this Tanka, adheres strictly to the Islamic epigraphic tradition, eschewing figural representations. The design is dominated by elegant Arabic calligraphy, typically featuring the Kalima (Shahada) on one side and the ruler's name, titles, mint (Bukhara), and date on the reverse. The substantial 35.4 mm diameter of this coin provided ample space for the engraver to render these inscriptions, often in a clear Naskh or Thuluth script, showcasing the high level of calligraphic skill prevalent in the region during the late 16th century.

Technical/Grading: Weighing approximately 4.5 grams of silver and boasting a significant diameter of 35.4 mm, this Tanka is a substantial piece. For optimal grading, collectors seek a strong, centered strike, ensuring all inscriptions are fully legible, particularly the crucial mint and date information. Common technical issues include slight off-centering, weak strikes in the margins due to the large flan, or minor planchet irregularities. A well-preserved example will exhibit crisp details, a pleasing metallic luster, and minimal wear to the high-points of the intricate calligraphy.
