Size and weight is always helpful. But in any case, the Arabic in this us very crude. I think it's a 20th century jewelry piece.
I agree with Ardatirion. When it comes to ancient/world coins you need to "read" how its made. See how its perfectly round, perfectly even strike, and a raised rim? These are only possible with machine striking. In that part of the world machine striking only started for the most part in the latter half of the 19th century. Therefor, knowing nothing else about the coin, except its arabic script, I can agree with Bill. See how easy that is? It will get easier the more you get into these, I promise.
I have seen "dancer suit" imitation coins in bronze, silver, and gold. All three are used for different costumes.
Similar designs on Kharubs from Tunisa and Budju from Algeria. However, it does not appear to have a date and has too good of a strike to match any illustrations I have seen. I tend to agree that it is an imitation.
