Please, one coin per post and expand pictures... Thank you, and best wishes for the new year! PS: the 2 Byzantine coins reverses are uspside-down
It's a bit late now, but I'll dig out the macro lens tomorrow for the Indian. Forget the Byzantines, I'll bin them. They aren't really collectable and a macro image of them would need a cinema screen to see the whole coin. Personally, I thought the images in the o/p would have been big enough to give an id. The bigger problem looks to be finding someone who knows what they are. Give it a couple days.
I think your DSC_0009 and 0010.jpg coin is a follis of Heraclius and Heraclius Constantine (610-641) from Constantinople. The other Byzantine is later, probably an "anonymous follis class 2" attributed to Basil II (976-1025).
The 1st coin is from India, I believe it is called a " 1 cash " It has GCE on 1 side which is the bale mark of the British East Indies company. Hopefully this information will get you started on the path to fully identify it yourself.
