The structure on the coins of Persian kings can not be Ka'ba-ye Zartosht; for the mentioned picture on the coins was not higher than 2 meters , had a two-stair platform and no stairway is seen below its doorway; its entrance door is much larger relative to the structure than that of Ka'ba-ye Zartosht; its ceiling has no steepness, enough to be put three fireboxes on; there is no distance between its doorway and the ceiling; it has no crowns or portals; and the dents showing the heads of its arrows are not more than six.
