I carnt imagine it being worth anymore then you originally paid for it unless you find the Right buyer.
i paid it at US$5, why it isn't worth? hahahaha btw, it still valid pagerank now check with : realprcheck.com or by using google search bar, type >>> info:
They are both valid pagerank, and fake pagerank. With www they are fake, without www they are valid. Could lose some value from it, so i would say $12 for pr3, $20 for pr4 good luck
