(Formule de politesse) The frozen date RY26 immediately brings to mind Sham Alam II. What did he perform so remarkable in his twenty-sixth year of reign around 1785 (AH1200), I do not know. There are quite a few coins venerating this RY26 in the IPS Awadh.
Do you have an idea for this Paisa (squared 18mm, 13gr.) ?
