Provisional "tanka" of 1/3 mithqal weight - Sultan Husayn Abu'l-Ghazi

Sultan Husayn Bayqara's long reign from Herat marked the last genuine flowering of Timurid culture, but his coinage reflects a monetary system under sustained pressure. The fractional tanka denominations — including this third-mithqal piece — were provisional issues, struck to address chronic shortages of small silver in circulation rather than as part of any systematic recoinage. Herat's mint was productive but inconsistent, and die alignment on fractional pieces is frequently irregular.

Husayn Bayqara died in 1506, and within months the Shaybanid Uzbeks under Muhammad Shaybani had erased Timurid rule in Khurasan entirely.
