My daughter found this coin while camping. We can't identify it. Could someone please help. It is very corroded, probably copper. It seems to have some form of Arabic writing on one side and two lions holding flags and some sort of crest with a smaller lion standing on top of the crest on the other. Any help would be appreciated.Thanks
