The earliest form of weighing scale relics was found in the Indus River valley, not far from Pakistan. The scales are approximately 4,000 years old and were used to access the value of gold and other materials that had an irregular shape. These scales had a plate at either side which was connected to an overhead beam. A stone was placed on one of the plates and the material that needed to be weighed was on the other plate to help judge the value of the material.
