I see that there is not a lot of answers...
With some reserve, my guess is that's a falus of Multan struck either by a Durrani ruler or by Sikhs ? (1st picture looks like a Sikh design); the lower picture could give "..(t)an " with a flower in the loop of the "N".
See this previous
thread and this detail of a falus of Mahmud Durrani which could have been struck at time when Sikhs ruled the area.
