Hi, Can you please identify this Arab coin, might be made of gold??

Weight: 2,78 grams.

Diameter: 27,3 mm.

It is N#79931 .

Or what is supposed to be.

Comparing the photos, I don't think yours is genuine, lots of small things are looking off. And measures don't match.

Thanks so much Giobruno for replying to my inquiry!!! 

 There was similar on here two years ago

The engraving of the Arabic is quite good on these, if a jewelers copy they often have deliberate errors or are more crude. The mint is engraved as  Qustantiniyah 

Here is one on zeno   https://www.zeno.ru/showphoto.php?photo=336940

here are a number of Ottoman coin jewelers copies, many have holes for threading

I agree with Vic65 yours is better executed than the one on the other thread linked by ZacUK.

And, as mentioned by Giobruno, in addition to the weight the numerals in 1223 are poorly executed.

Thank you all for your help!!!
