Terra cotta tokens or tablets from Harappa. In Area G, south of the recently discovered gateway on Mound ET(20), excavators found a concentration of as many as 31 identical cylindrical terracotta tablets (top center), but it is not known what they could have been used for.

Concentrations of tablets recovered through recent excavations at Harappa indicate that these tablets become popular during the late part of Period 3B (2450 B.C) and continue on into the final phase of the Harappan occupation, Period 3C (2200 to 1900 B.C.).
