Well coins they are already on the stock exchange and are used in some countries, payable, etc...a token is kind of the same coins but they serve specifically to the ICO and no where, but the point is that if they are used somewhere else they, too, are coins.
Do I understand correctly?
I don't really know the difference between token and coin but I think coin and token are both the same. They can also different the way the developer called the currency they made.
