@hh, I think what @peter1234 is really asking is after seeing the differences pointed out between fakes and the real thing multiple times, why don't you feel more confident making these determinations on your own? Of course we are happy to provide our opinions to you as many times as you would like, but ideally we would help educate you to the point where you know the answer on your own. For example, is there anything about the rim or letters or the hair of the bust or the denticles that is unusual to you?
As a side note, since this coin is so expensive when real and has been extensively faked, I personally would never purchase it unless slabbed (and even then I would be very cautious). I recognize that the coin market in North Africa is a bit different than the US, so this might not be possible for you.

The coin is counterfeit. Look at the raised rim on the coin . The coin was struck in a ring and rings were not invented until the 1830's, so the coin has to be a counterfiet. Compare it to a genuine example and you will see the difference in the rim and denticles.
