It has been speculated that pieces of metal weighing a deben were kept in boxes,^[4] taken to markets^[5] and were used as a means of exchange.^[6] Archaeologists have been unable to find any such standardized pieces of precious metal.
On the other hand it is documented that debens served to compare values. In the 19th dynasty a slave girl, priced four deben and one kite of silver, was paid for with various goods worth as much: 6 bronze vessels, 10 deben of copper, 15 linen garments, a shroud, a blanket and a pot of honey.^[7]
