Through SWAG, B/O and showing off on trades, I have found the amount of people pay for this unique hat these days.

Best link to prove the current best pure offer is http://www.tf2outpost.com/trade/9234614 - 12 pure buds has been offered by CrazyCar (1 week ago)

For some reason this trader won't take the 12 pure offer, because of his inflated b/o.

Other decent trade got some offers, but still not reaching the 12 wanted pure and being rejected - http://www.tf2outpost.com/trade/8040703

I suggest the price at 11.5 to 12.5 pure. All other links in general have offers of 11 pure rejected. Every trader beside his inflated b/o is heading for 12 buds. Comments about big-big unusual overpays from 14 to 16, which are generally rejected or retracted, are just senseless and don't affect the price a lot.
