The date on the coin is AH 894 (1489 AD). Jaunpur sultanate was taken over by the Lodi Dynasty of Delhi sultanate by then. So i believe this is a coin of Lodi Sultanate. Now the AH 894 is when Bahalul Lodi ended his reign and Sikandar Lodi became king. So this can be of either of them.
Hope this helps
