Old coin from France 1754

I want to know more about this old coin. Please help

Why only show one side, and what is the diameter?
Help us to help you.

As ZacUK posted, you need to show both sides and cropped. As well as diameter, weight is also helpful.
From the image provided it appears to be a token rather than a coin. Maybe this one, depending on what's on the reverse?
