Over a year out of date. Retired hat, going for well over current price on the steam market. Vast majority haven't moved recently, but two have apparently moved this year:

HAT 1:

http://backpack.tf/item/622170200

Sold on market so it doesn't show up currently, whoever bought it isn't indexed.

Sale X: Not usable

Went to Sargent¥ (MCT) ⇋HG-A⇌ in a gamble

Sale X: Already used elsewhere

I purchased this as part of an offer on my strange cats, and it was somehow used to justify a price of 110 for the cats? Didn't require any minis despite the fedora price being way out of date, and missed several keys of sweets. Foamy was just winging it on that estimate.

Sale 1:

Sold on steam market for $55 to buyer, $47.83 to seller

= 19.5-22.5

HAT 2:

http://backpack.tf/item/1150452948

Sale 2:

http://backpack.tf/profiles/76561198196081558#!/compare/1464998400/1465084800

Sold for:

-Pro KS Australium Axtinguisher (8 keys)

Seller at 7.9 (many at 8), buyers at 7.1 and 7, community market ~$19-22 (~7-9)

-Spec KS Australium Frontier Justice (Manndarin) (10 keys, sellers at 10, buyers at 10)

= 18 keys

Blutsauger and everything else added to seller (except a single low-value skin) were part of this trade instead:

This trade involved swapping spec aussie Frontiers (Manndarin -> Team Shine), and explains why the histories initially look weird on the FJ from the listed trade.

Sale 3:

http://backpack.tf/profiles/76561198153887150#!/compare/1465257600/1465344000

Sold WITH PKS Aussie Axtinguisher (8) for:

Miami Sober Stuntman (17-18, close to outdated) + ~1 key sweets,

= 11 keys?

Big outlier, wonder if everything was spotted by backpack correctly there?

Outdated info from last suggestion:

Supporting choice of outliers and high end, there isn't a single unusual Fancy Fedora listed on backpack classifieds or outpost for under 23 keys. (The only one listed at 23 is steaming, http://www.tf2outpost.com/trade/28234090 , and briefly the one in sale 1 at 23 keys, before it sold on market within about two days http://www.tf2outpost.com/trade/28202061 )

Update: Has been one listed on the classifieds at 18 keys since the 12th (was initially listed at the same time as this trade: http://www.tf2outpost.com/trade/28251134 ), capping at 18.

Sales at 11, 18 and 19-22, calling 11 an outlier and capping at 18 based on buyout.
