It is prety strange, becouse I really searched all availagle databases and I didnt find the exactly same coin. There is only different variations of the "genio avgvsti" side of the coin, but not this exactly. It looks prety much like this one:

... but not the same.
By the way the both sides of the coin are reversed at 180 degrees. Is this something normal for ancient coins, or it is a sign that the coin is a fake one?
