I wanted to ask for help from my expert Numista friends in hopes that you can help me identify there 3 coins that I recently acquired. My understanding is that they are from the Indian Sub-Continent, though any other information on them would be much appreciated.
Starting from left to right, the first coin weights 2.9 gram and measures 20 mm in diameter. The second coins weight 2.8 grams and also has a diameter of 20 mm. The third coin weights 3.4 grams and has a diameter of 27 mm. I believe they are made of copper. See the pictures below.


Thanks in advance for your help.
Dan
