I agree with the coin being that of one of the links posted. On the last picture, and on the second line to the bottom (farthest left area), it appears the 1/2 kurush has two arrow-things, and the 1 kurush has three. Your coin has three, so I would think 1 kurush, but that could just be some different variety. To be sure, check the diameter: 1 kurush should be around 38 millimetres, and 1/2 kurush should be around 28 millimetres.
