I don't know why some are black and some red but I am fairly confident that the red is less common. I have never seen any disparity in terms of price/value between the two colors. I think Lee Behrens can give you some data that backs up the relative scarcity of the two backs -- it likely has to do with which factory produced them as I recall (I guess that's sort of a reason.)
