Well judging by theymos, he was selling hacked account, so the price shouldnt be considered as a legit one.
if you want to know real price, you can try open buy order in marketplace
open a WTB Legendary Thread than some people will PM you to sell
It's kinda lame to claim you want to buy something, withouth real intention to do so.
Found some threads, but doubt they are legit ones also:
