recently bought then sold this hat, then then decided to research :/

i paid 30 usd for the hat following backpack pricing keys at 1.83 usd per key. is around 16 keys. http://www.tf2outpost.com/trade/11166334

there is under a page of these on op with marginal offers around the current range, and many many offers in the new range.

unusual overpay factored by taking median value then multiplying by .9 (aka 90%)

http://www.tf2outpost.com/trade/10259054 offered: bubbles big country (16.2) and bubbles fruit shoot (15.3)

http://www.tf2outpost.com/trade/10692365 offered: s machina if owner adds retracted? calling it 16.

http://www.tf2outpost.com/trade/11107742 offered 22 by http://steamcommunity.com/profiles/76561198055015993 who now owns a baziliion bp expanders

in short im loath to expand the range however i purchased for around 16, and there is a 22 key offer, which im calling 20 since the offerer doesnt have pure. so .9 multiplier. also unwilling to change the range that much with only one sale.
