Kosi is located in Chhata tahsil of Mathura district. Presently the town is better knows as Kosi Kalan in the Braj region. Unlike Kaman, Kosi does not have any major religious significance, but is important as a commercial center. The existence of a rupee and paisa of Kosi mint make us rethink the attribution of certain rupees which Wiggins and Maheshwari attributed to “Gokul”.
