Re-suggesting due to some advice from Polar. My initial price suggestion was 12.5-14, but polar pointed out I was missing some sales at 12. He explained it best, so here is what he said:

"Every single clean sale in the last two months (not counting complex sales involving high tier hats) --

http://www.tf2outpost.com/trade/24006358 - secret fez + 2 ~12

http://www.tf2outpost.com/trade/24465184 - 11 pure (sold in a day)

http://www.tf2outpost.com/trade/24543010 - 12.5 pure

http://www.tf2outpost.com/trade/24626342 - this is the brigade trade (you don't need to apply overpay on the 8.33 for the brigade because that was its pure value - ~13.3

http://www.tf2outpost.com/trade/24519639 - offered with ~2 buds in sweets for duped beams CM ~13.5-14 (mini for that here - http://forums.backpack.tf/index.php?/topic/6817-bpbs-mini-suggestion-thread-for-gifted-duped-hats/) ~12

http://www.tf2outpost.com/trade/24157565 - your sale of 7 pure + beams merry ~14

http://www.tf2outpost.com/trade/24717732 - your sale which is probably close to 14 given how outdated the fros are

So that gives us sales at 11, 12, 12, 12.5, 13.3, 14, 14. I'm fine calling 11 an outlier. But 12 won't be one. Range should be 12-14 here."

Thankyou Polar
