Price of Each Pagerank Website ?

Hi,

I am about to design a kind of website appraisal tool that one of the factor is the pagerank.
But i have no idea about the value of website which has some pagerank, for example PR 3 website price range is from $A to $B.
Does anyone have some information about website price of
PR 0 website : +$0.
PR 1 website : +$? - +$?
PR 2 website : +$? - +$?
PR 3 website : +$? - +$?
PR 4 website : +$? - +$?
PR 5 website : +$? - +$?
PR 6 website : +$? - +$?
PR 7 website : +$? - +$?
PR 8 website : +$? - +$?
PR 9 website : +$? - +$?
PR 10 website : +$? - +$? (just estimation)

Thanks.

 

IMO, PR has little to no value anymore. Those are just #s mate.
