1/4 Tanka - `Miri` - Timur Herat

The Timurid mint at Herat was among the most active in the Islamic world during the reign of Shah Rukh, who controlled the city from 1405 until his death in 1447 and made it a center of Persian cultural production. The small silver miri denomination — essentially a fractional accounting coin — circulated within a monetary system that relied heavily on the tanka as its base unit, with fractions struck to ease small-scale transactions in the bazaar economy.

Album 2407 covers a relatively tight range of Herati fractions from this period. The Zeno catalogue record for this piece provides the primary die reference for collectors working below the tanka level, where documentation remains thinner than for the main series.
