I was offering around on op offered on this hat and checked its price, i was blown away it was so outdated

B/os on op

http://www.tf2outpost.com/trade/19109490 - 4.5 buds open here too- http://www.tf2outpost.com/trade/18974586 appears to have been bought for 3 pure- http://www.tf2outpost.com/trade/18914669 in a day or 2

http://www.tf2outpost.com/trade/18593139 - 4.45 buds, 3 weeks unsold

http://www.tf2outpost.com/trade/17176933 - 6 unsold for 2 months~ appears to have been bought for a Miami armored 2 moths ago 4.4-4.5 buds- http://www.tf2outpost.com/item/440,2270416792,445,5

http://www.tf2outpost.com/trade/17352331 - no b/o unsold for 2 months~

conclusion- only 1 recent sale, sold for 3 buds in a day~ seems like an extreme quick sell. 2 b/os on op are for about 4.5 buds last valid sale i could find was a miami armored authority which is valued at 4.4-4.5, however i don't know wether it was offered or not. 4.4-4.5 seems like a good conservative drop. can be updated more with more sales/evidence
