Ottoman 1/2 Cedid Mahmudiye ?!

I think the diameter of the gold coin would be 15 mm. Plus I don't think the denomination is written anywhere on these coins, so I would guess it is a smaller denomination from that same mint.

Hello, Ive made a mistake it is the same size as a 10 euro cent so about 20mm.
But what is the purpose to make a good fake copy of a small coin ?

While we are waiting for @kushanshah ...
As best I can tell (from my old Craig catalog), we have these dimensions for the series of gold coins issued in the regnal years 26-32:
1/4 Cedid = 13 mm, 0.38-0.4 g (C.239, KM643)
1/2 Cedid = 15 mm, 0.7-0.8 g. (C.240, KM644)
Cedid = 20 mm, 1.56-1.6 g. (C.241, KM645)

The Numista photo for the 1/4 Cedid is better than the one in the NGC link, and allows us to see that your coin looks very close to this one. https://en.numista.com/catalogue/pieces34889.html
So, you have a coin with the dimensions of a 1 Cedid (20 mm), but a weight which is too low by 50%, which is what would happen if a coin were made with the same diameter and thickness, but using silver instead of gold.

While the design elements are the same, it looks like the execution of the design in the Numista photo is much finer, i.e. your coin has thicker font for the inscriptions and toughra.
Since I have not been able to find any silver issue with this design, my guess is that this item was a forgery which at one time was gold plated to resemble a 1 Cedid coin.

Thank you very much @tdziemia !!
