 I don't think there is a back multiplier chart anywhere. I have seen some super high prices on some scarce backs recently and some relatively low prices on others. You might be able to do a few board searches for rarity levels. I came close to finishing my back set (except for a few variations) many years ago. I think they are fun to collect.  Those rarity levels have changed over time with new "discoveries" of certain ones.
