Abstract During the excavation of Tol-e Sangi in southern Iran, tokens and a sealing were discovered in Pre-Pottery Neolithic (PPN, c . 7050–6900 BC) layers. As the oldest sealing found in Iran, this artefact suggests that storage and sealing practices were used during the PPN period in South-west Asia.
