http://www.tf2outpost.com/trade/25495993 - Is biased because when he was selling buds they were 9.5 keys, but now they are 8.

http://www.tf2outpost.com/trade/25455768 - B/O of 9 keys unsold for 1 week

Your sellers at 9.5 or less:

http://www.tf2outpost.com/trade/25525524 - Sold within 1 day, without bumping, quicksell;

http://backpack.tf/profiles/76561198021383012 - Sold within a day, assuming Not Sterling Archer's "3. 33 minutes old" was this guy;

Your "unsolds" at 10 key:

http://www.tf2outpost.com/trade/25484367 - Sold, took a couple days; (his backpack http://backpack.tf/profiles/76561198017911615 )

http://www.tf2outpost.com/trade/25507449 - Sold in a short time, 3 days (his backpack http://backpack.tf/profiles/76561197960906194 );

http://www.tf2outpost.com/trade/25543407 - Changed his B/O for tomi, now 14 keys ( http://i.imgur.com/Fy2wvxW.png , incase he changes B/O again) so its invalid proof;

http://www.tf2outpost.com/trade/25504280 - Poorly bumped, maybe reason why he hasn't sold;

But http://www.tf2outpost.com/trade/25455768 , provided by ( http://backpack.tf/u/76561198094818081 , comment right above mine) is a good unsold at 9 keys. Unsure if he dropped price in the meanwhile or if he bumps often, doesn't seem to bump often.

Overall 10 keys sells, takes a while but not 1 week, and 9-9.5 key sellers appear to be quicksells.

10 keys should be in range, downvoted from my part.

I sold mine w/ spec ks in 12 keys :s
