Scorching El Jefe - Recently priced at 363.5

Purple Confetti Exquisite Rack - 60 (Probably too high at 70 considering 4 month unsold and the rest of the unsold.

Purple Confetti Soldier's Stash - Recently priced at 48

Final price = 471.5 keys.

Reselling it for 450.

Mini for the rack - https://backpack.tf/profiles/76561198105583712#!/compare/1520035200/1520121600 (Sold for 59 keys pure) Rounding up.

B/O on outpost says http://www.tf2outpost.com/search/273545452 - 430-450 pure but it was listed on backpack for 450 pure.

Capping at 430

Second sale -

Sold within 2 days. On such an expensive item, I'm not sure if it's the correct call to ignore the B/O.

Mini's:

Dead Presidents Soldered Sensei (13)

Multiple sales around ~13-14 keys, though the majority (2) is at 13 keys. Taking 13 keys.

Sold for a Circling Hearts Towering Pillar of Hats.

https://backpack.tf/profiles/76561198192602363#!/compare/1524268800/1524355200

Tower sold here for a Stormy Dapper + 9 keys. Dapper has sellers around 33-34 keys so taking 40 keys for the Rifleman seems fine.

DUPED Green Energy Veil = 205 keys

Gonna take a risk here and put a mini that's 5 months old. No other valid sales on this hat. Bought for a PE Attendant (~55) + ~3 keys mixed = ~74, rounding to 75 keys.

https://marketplace.tf/items/213;5;u10

Attendant has 3 sales here ranging 45 - 63 keys, so taking the average of roughly ~55 keys.

https://gyazo.com/ac8fa7eb8319c98befd05b24a44ac652

Taking 16 keys for the Tavish, based on a matured listing.

Frostbite Tin Topi = 27 keys

https://gyazo.com/27a417d8ae8145e7ae8606a202a33d6d

Not really any proper mini on this hat, so taking current (matured) listing.

Sunbeams Master's Yellow Belt = ~130 keys

https://backpack.tf/profiles/76561198119634686#!/compare/1518739200/1518825600 - sold for 126 keys, took a while.

https://gyazo.com/3c82e535828233055df507ee0606a586 - Sale at 124 keys and at 130 keys.

Looking at the current market, I'm going with 130 keys. Arguably not the best mini around apparently this isn't really being traded a lot.

Mini for Death at Dusk Warpig = 140 keys

https://backpack.tf/profiles/76561198074192315#!/compare/1524441600/1524700800

This trade also supports ~140 on the Warpig, given how the unusual weapon sold for about 40 earlier.
