Two stone weights, which are large rounded stones (pebbles) with signs applied to them, found in archaeological excavation of Gorgippia Weights belong to the Hellenistic time. The first weight with the inscription ΤΡΕΙΣ (three) weighing 1 518 g corresponds to three mines of the Persian weight system. The second weigh weighing 5 730 g has a sign Μ (40), indicating the weight of fortythirds of the mines of the Euboean-Attic weight system.
