I have looked at about a dozen different sites trying to Id this coin? I cannot find a date or denomination on it. It weighs 1.55 grams, is 19 mm in diameter and less than 1mm thick. Looks the be made of brass It appears Arabic to me, I will call the obverse the side with the star. There is a star in a circle at the top of the coin. Maybe it is a 1 below it with some Arabic writing around it. Either side of the star are branches. On the revers inside the circle looks like a crescent moon at the top of the circle A diamond at the five o'clock position. Not sure what the rest is. There is Arabic writing on the rest of the coin.
