This. They weren't wasting ivory on junky razors back in the day, so materials like ivory and tortoise are usually a guarantee that the razor will be good, as long as it is in decent condition.As many have already stated, your pictures make the scales look much more like bone. I have both bone and ivory scaled razors. I chased ivory for a while, but I'm ho-hum on it now. Sure it may command a small premium if I run across it, but not by a whole lot. The only thing I can speak of regarding Ivory scales is that the blades affixed to them were usually of better quality than lesser materials like wood or bone.
