A land donation deed of Sher Shah Suri has also been recovered. It also has the official stamp of the Suri empire and is written in French language on jhamani ink on bhurja patra.

Archaeologists believe the coins date back to the era of Alauddin Khilji and Sher Shah Suri’s son Islam Shah Suri. The coins were seized from three labourers who had sold some of them.
