Note: Shams ud-Din Iltutmish, the third Sultan of Delhi and a ruler of the Mamluk dynasty, is widely regarded as the true founder and consolidator of the Delhi Sultanate. He transformed a former Ghurid military outpost into a stable empire by establishing Delhi as the capital, introducing key administrative and economic reforms such as the iqta system and a standardized silver and copper coinage (tanka and jital), securing recognition from the Abbasid Caliph, and successfully defending the Sultanate against Mongol incursions. Under his rule, Delhi emerged as a major political and cultural center in northern India.

The present silver tanka exhibits a distinct and previously unrecorded feature. Unlike the preceding type, the mint name "Dehli" appears on both the obverse and the reverse, placed prominently in the upper field. Such deliberate duplication of the mint name across both sides of the coin is unknown in other recorded series and may represent an experimental issue, intended to emphasize Delhi’s political authority and sovereignty during a formative phase of the Sultanate.

This type is distinct from the previous lot and represents the first documented appearance of this exceptional variant in a public auction, significantly enhancing its numismatic and historical importance. As part of a recent series of discoveries from the reign of Shams ud-Din Iltutmish, it offers advanced collectors of Delhi Sultanate coinage a rare opportunity to acquire a newly recorded type.
