Calculation:(combining the pure item minis first/items that sell for pure)

6+170+19=195 keys

(21+10+1.7+5+3+8.5+37+85+46+135) = 350.2 rounding down to 350

350*0.9=315

315+195=510 keys

Minis:

Vintage Specialized Killstreak Lugermorph

http://steamcommunity.com/market/listings/440/Vintage%20Specialized%20Killstreak%20Lugermorph - Lugermorph sells for ~7.5 keys

http://backpack.tf/stats/Vintage/Lugermorph/Tradable/Craftable - Sellers on classifieds at 5 keys

5 keys seems like a quicksell and 7.5 is too high, using 6 keys.

SF Scattergun:

http://backpack.tf/vote/id/552e7feab98d88ad138b51c5 - Sells on classifieds at 19,20 as well, 22 keys looks super hard to sell so using 21 keys.

Searing Pomade:

http://www.tf2outpost.com/trade/25577976 - Sold along with DP Mancer for searing stash.

Mini for stash:

http://www.tf2outpost.com/trade/24865787 - Sold for 8 buds+mk.II gold sniper, Buds were 9.5 keys.

9.5*8=76 keys, 76+gold sniper = rounding up to 80 keys.

Since mini is in pure im not calculating overpay on stash.

80-36=46

Pomade=46 keys
