Oldcardboard has the "Value Multiplier" at 1 for each of the three sets indicating that their value is about the same.

But this doesn't seem to match the availability as T213-2's seem to be more common and the asking prices seem to be higher for T213-1 and T213-3. Assuming that the Oldcardboard site is wrong, what would you say is a true value multiplier for these three sets?
