1691 French coin . I'd please

I

 Please show a picture of the other side, along with the weight and diameter.

The coin is encased  between 2 sheets of Plexiglas so it's not possible to get a photo of the back or to weigh, but diameter is 1 inch approximately 

I think it might be this one. 
N#16312

Hello Mike,

 something more precise than an inch would help to narrow the unit. Plexi looks transparent both sides is the coin in a museum or something?

iam a bit lost with the text. Too much letters above the head Usually that where you have a sun. Text should be
LVD. XIIII. D. G   (Sun)  FR. ET. NAV. REX

over strike ?? Letters on top don’t looked aligned What look like a A is upside downs 

On Numista, if you change the language on the website to french, then send a message to the forum it will be published to the French forum. More likely to get specialist of this period.

have a good day

It's my coin and the back is reflected in a mirror so it can be seen, but almost impossible to photograph. Because of the wear it is hard to read for sure.  I'm going to see if I can figure out how to translate.

Mike, 

if you want more info, I’ve sent you a PM with French translation for you to create a post on  the Numista French forum. 
 

Good day.
