This is as close as I could get and similar at best. The diameter and weight of your coin is confusing as if it was “clipped” for silver content at one time.

Good luck.
Dear Harryg,
Thank you very much indeed! Yes, the legend seems accurate. However, even though it may have been “clipped” there are extra 2 grams:) Maybe it could be a 6 Shahi coin…
Thank you again!
