yes i own one. if you are not familiar with this unusual please see: http://one-crate-per-week.tumblr.com

so there's 2 of these. one is mine ( http://backpack.tf/item/1983470822 ) and will never be traded

the other one has gone through a few questionable hands ( http://backpack.tf/item/1944465189 ).

here, however are the 2 most recent sales of the same hat:

sale 1: http://www.tf2outpost.com/trade/25714603

memory leak handle (14 keys) (bordeline 3 month old price but cheap enough it shouldn't matter too much)

aces high bolted bicorne (currently 26 but price is 7 months old and my mini shows it's more like 20)

20 + 14 * 0.9 = 31

seller: http://backpack.tf/profiles/76561198115080273?time=1429254000 (the keys and paint were not part of the transaction)

buyer: http://backpack.tf/profiles/76561198077327769?time=1429426800

mini for bicorne: difficult because there's only one that's recently been resold - the one that was used in the above trade. here's a recent sale on that not involving a banned user...

http://www.tf2outpost.com/trade/25515642

this one was traded for a TW Toque (~20 keys but also an old price) 3 weeks ago

seller: http://backpack.tf/profiles/76561198070258280?time=1427612400

buyer: http://backpack.tf/profiles/76561198090938224?time=1427526000

seller wanted 20 keys pure but these guys are all kinda silly tho so i'll just take the bicorne value at 20 keys

http://www.tf2outpost.com/trade/25760476 - the current owner has had it for more than a year: http://backpack.tf/profiles/76561198067960572?time=1396249200

i don't have premium to do research on the other AH bolted bicorns. if someone has a better insight on that hat's value let me know.

sale 2: http://www.tf2outpost.com/trade/25740754

offered on miami company man (33 keys) (19 day old price so very fresh)

buyer: http://backpack.tf/profiles/76561198145126174?time=1429513200

seller: http://backpack.tf/profiles/76561198077327769?time=1429686000

ya, i was kind of hoping for 33 keys solid on this hat 'cause it would be such a hilarious coincidence (it took 33 keys to unbox mine) but 31-33 seems better.

PLEASE READ: if you can help with the bolted bicorne mini or have another idea for this suggestion please comment with corrections and don't counter suggest - this hat has a special place in my heart and it would be a suiting end of the one-crate-per-week saga for me to be able to price it - thanks in advance!
