4 Coins For Identification - 2 Indian, 2 European?

Bottom Right: Grantham, Lincolnshire trade token;
HALFPENNY TO BE EXCHAING / BY YE OVERSEERS OF YE POORE / GRANTHAM / 1667

The square one: given it's very rough appearance and the observation that it doesn't appear to be made of silver, I'd agree that it's an Islamic "temple token" from India, in the style of a square rupee of Mughal emperor Akbar.

The Nuremberg rechenpfennig isn't going to be worth too much with the hole like that, and the temple token probably not too much, either, in that condition.

The EIC Bengal Presidency pice catalogues at a couple of dollars in that condition.

British tokens of the 1600's are pretty scarce outside of Britain, but so are the people that collect them (the "Conder tokens" of the 1700's and 1800's have a much broader collector base). I don't have a current catalogue for these, but my 1970 British token pocketbook catalogues it at 75 pence. Today, I'd guess 10 dollars at most, probably less.
