It's the weight that confuses me,Paisas during Aurangzeb & Muhammad Shah weigh 12-14g although Dams reappear during Muhammad Shah at 17-19g
the average weight of the coins is around 18g which would fit for Elichpur. Also for Alamgir II
Of the 4 coins shown, look on the right image, bottom left coin has what appears to be 78 which doesn't make sense if it's part of a date
I think I need to post all 12 coins,particularly the 6 rectangular/square ones as there might be something worthwhile amongst them
