Can anybody identify please ?

Yemenite states ? Post the other side.

Welcome to the site.
Apart from the other side, what size is it please?
The ١٣٤٣ date (1343) is 1925 equivalent anyway.

EDIT: I agree it is Yemenite states, and putting ١٣٤٣ in Search showed
42 results and these two look most like your picture, so need to see other side also ...

https://en.numista.com/catalogue/pieces11742.html Diameter 21mm 1/80 Riyal (1911-1942)
https://en.numista.com/catalogue/pieces11744.html Diameter 29mm 1/40 Riyal (1923-1948)

Here is the other side,it is well worn..it measures 2.5 cms.

Thanks; I added a minute ago to my earlier reply, and your coin has the one star below
the reverse, making it similar to the second coin I linked to, the 1/40 Riyal.
I made cropped and rotated images to compare easier ...




Still might not be your coin, especially as yours is 25mm and the two
mentioned earlier are neither that size; but country looks right.

Thank you,I have had it for about 20 years and had no idea what it was.
