Quite often I see a 1st level mat selling for more than a 2nd level one of the same type.
Why ?

Do you actually see them selling or just listed? Because when you sell a T1 item on the AH the default behaviour is that it just recommends the lowest price of the T1 variant of that good. So it does not check if T2 is cheaper, and you don't actually see that unless you search for all qualities first. And since the T1 don't actually sell (as T2 are more common and cheaper) the price it is listed on does not really drop.
there are some vendor items, quests, etc that require mats of specific quality, mostly rank 2 but I think there was a rare that could only be summoned with a rank 1 mat (my memory's a little rusty though). this can have some effect on the demand for lower quality mats
