Comment : This unlisted silver ½ tanka of Shams-ud-din Iltutmish, struck in the name of the Abbasid Caliph al-Mustansir Billah, is a previously unpublished variety not recorded in Goron Goenka. The coin is finely struck, prominent for its full Kalima, complete caliphal titulature, and sharply defined double-square margin design.Part of a recent series of discoveries from Iltutmish's reign, this rare and highly unusual type presents a unique opportunity for collectors of Delhi Sultanate coinage to acquire a newly recorded issue of exceptional historical and numismatic significance.
