The seals were pressed into soft clay to seal the mouths of jars and, as suggested by the imprint of fabric on the back of some seal impressions, were used to create clay tags for sacks of traded goods such as grain. Indus Valley seals have been found as far afield as Mesopotamia (present-day Iraq) in the cities of Umma and Ur, in Central Asia and on the coast of the Arabian Peninsula. A large number of seals have been found at the port of Lothal in western India. Finds of Mesopotamian weights in Indus Valley cities confirm that trading took place between these two civilisations. Some experts believe that Mesopotamian written records of trade in gold, copper and jewellery may be referring to the Indus Valley.
