Taking recent sales only. The only one in the market is duped.

Sold for a Blizzardy Storm Team Captain (5.1 buds) - most probably inexperienced in unusual trading and didn't wait for more offers (trade was opened and closed 2 weeks ago, could've gotten more imo:

Sold for an Overclocked Modest Pile of Hat (no price):

http://www.tf2outpost.com/trade/13052324

had offers of:

Secret Fruit Shoot (4.7 buds)

Stormy 13th hour Helmet Without a home (3.9 buds) + steaming brown bomber (2.1 buds) ~ 6 buds

Cloud 9 Fez (4.2 buds) + Peace Phantom (2 buds) ~ 6.2 buds

6 buds pure

*Assuming his C/Os are all true even though there isn't any proof. This is because even though it wasn't on his trade, the C/Os seem to be legit due to the fact that he listed the overclocked modest there too (it wasn't offered on his trade).

Also, he apparently sold the modest for a terror-watt luchadore (8.4 buds, not sure if anything was added). Though the modest sale can be considered an outliner here (this is to show possible reasons on why he rejected the 6 buds pure?)

In the previous suggestion (http://backpack.tf/vote/id/51cbf7faba2536b04e00000c), Tyra mentioned that he bought the Ushanka for Roboactive Private Eye (4.7 buds mid range) + small sweets. ~ estimate to be around 4.8 buds

In this trade: http://www.tf2outpost.com/trade/12184011 , the owner mentioned about the previous sales of this hat. One was the roboactive private eye, and another is a burning lucky shot (which I really doubt). Unsure of what he sold it for.
