This variety is probably from the mint of Ujjain - the crude mint name is sometimes visible on the bottom of the obverse. 

Old style tankas in the style of Sultans of Malwa continued to be struck at the newly acquired territories by Akbar until ca.1000 AH at Mandu, Ujjain and Ujjainpur (and the copper coins were minted there until the reign of Jahangir and Shah Jahan). After ca.1000 AH the silver coins were replaced by regular Imperial issues. The silver tankas are usually mintless and dateless. Where a part of a mint can be observed, it is usually very crude "Mandu" or "Ujjain", or very crude word which cannot be read. Because of this uncertainty, the term Mandu-Ujjain has been used for this series.
