Citeer: "dltcoins"1: bull & horseman jital, difficult to be more specific due to grade.

There are many, many varieties of bull and horseman coins. Tye (Jitals, 1995) lists nearly 70 major types with the bull on one side and the horseman on the other, differing in inscriptions and style, spanning some 500 years. Unfortunately, I don't think a specific attribution is possible beyond perhaps "post-Shahi, c. 900-1200".
