You are one of a small group of serious collectors of Mughal coppers. I am getting the impression that is a wise choice, as so much remains to be discovered in this field. The struggle of traditional coins against the denominations introduced by the Mughals for all their lands seems to be one of these underreported stories.
In addition, I am very impressed by the maintenance of the weight standard of the silver rupee during centuries. To me, that almost mechanically means that the copper coins are variable in weight. I would say that it is for experts like you to plough through these weight differences, sort out the denominations behind them and end up with something that will tell you an untold story of price levels in India. Have fun!
