please help me identify this Islamic coin

its silver and weight nothing 

Welcome to numista.

Please read the forum policy before posting. Of course the piece of metal has a weight, diameter and thickness!

Please crop the images, we do not need all that useless background. https://pixlr.com/fr/remove-background/

A coin is not Islamic, since the word Islam describes a religion, not a geographic region. The signs on the coin are Arab words written in the Arabic language!

I think it is an Ottoman Acke, that pretzel knot can be found in several ottoman coins

Higher resolution pictures may be helpful,from the second picture I can read from the second picture the word أحمد which is Ahmed, the first picture low resolution  makes it very hard to even guess.  

If it reads Ahmed, might be
