How much is my Lockerz account worth?

Hi all. I know it shouldn't be done, thoretically, but I would like to sell my Lockerz account to my friend. The account has more than 10thousand legit PTZ, and it is in the Z-List (I've only seen a few videos, so it would be possible to earn even more PTZ). I read somewhere that in 2010 a PTZ was worth something like 0.06$ (in this way, my account would be worth more than 600$); but now, we are in 2011: does some of you know how much could my Lockerz account be worth?
