"Finally doing this"

Resuggesting, based on corrections and an additional sale [of which I was previously asked not to use it, thus I did not investigate it any further until I was provided with the context of the sale]. Credits to Morxx for providing missing/additional info!

Was requested to do this a while ago. Was waiting for more sales due to an outpost seller conflicting with the sale I had. Have been asked to do this hat on multiple occasions after that

SO HERE IT IS, the apparently desperately desired update.

The sales

Sale 1

Sold for secret bomber (~380) + burning AA (~170) + beams defiant (~69) + 10 keys

http://backpack.tf/profiles/76561198024925599?time=1435129200 after

No overpay, offered

380+170+68+10 = ~628

-> 629 keys

All hats have been capped at its buyer's or seller's pure buyout value [apart from the hallmark] where they were outdated and where it was deemed necessary. Since most of them are a relatively small portion of the sale, this should be close enough to represent their value for this sale.

Mini sale 2

Mini hallmark:

Unsold 128 [1 month]

http://www.tf2outpost.com/trade/26650420

Sold fast for 100 pure:

http://www.tf2outpost.com/trade/27007923

100-128, averaging to ~115

Taking 115.

0.9*(234+115+20+30+33+22+12+14+13+14+9) = ~467, rounding to 470

-> 470 keys

Sale 3:

Sold for ~500 in mixed pure/cash

Quoting Morxx from my comments on the prev. suggestion:

"Additionally, I paid 501 keys mixed cash/pure for the BoA:

http://imgur.com/QhiRjxZ $90 $1.8 each (50 keys)

-> 500 keys

Sale 4:

Sold for gifted GBH antlers:

http://backpack.tf/profiles/76561198123917552?time=1442175051 before

http://backpack.tf/profiles/76561198123917552?time=1442300400 after

No usable sales on the antlers. Last sale on it was for a MG polar, which is currently priced ~300.

Either way, theres no way to accurately display the BoA price with this sale.

Sale 5:

Sold for ghosts neckwear (~275) + GBH uberstern (~60) + frostbite boxcar (~160*)

* Overly extensive boxcar mini below. Probably a tad low for the boxcar, but it'll do for the suggestion

0.9*(275) +160+60 = ~470

-> 470 keys

=================================================================================================

Mini boxcar

Sale 1:

Excluding the 620 sale because of it being unsold for 500 for a month:

http://www.tf2outpost.com/trade/26820237

620 sale is also ~3 months old

Making a range 470-500

Constructive criticism welcome!
