8 months old price. Most trading right around 6.4-6.8 in unusuals, 1 offer of 8 pure in the last month justifies a slight bump. Proof includes 3 actual sales plus current offers.

Actual sales:

6.4-6.5 in unusuals - http://www.tf2outpost.com/trade/9141227 - traded for blizzardy killer exclusive + sweets

6.75 in unusuals - http://www.tf2outpost.com/trade/8981881 - traded for flies marauder

? in unusuals - http://www.tf2outpost.com/trade/8991011 - traded beams fruit shoot + beams tyrants (9.4) + beams beanie (3.25) + smoking company mann (2.2) for knifestorm tc (23.2) - not including this complex trade in the pricing, may have also involved sweets

Current Offers:

8 pure - http://www.tf2outpost.com/trade/5589731 - 8 pure offered 1 month ago (more current than the current price that was set 8 months ago)

http://www.tf2outpost.com/trade/9160109 - seller willing to sell for 6.5 pure - offered on my trade

In summary, setting a low value of 6 in pure given multiple deals in unusuals in the 6.4-6.75 range. I think the pure of 8 seems a bit of an outlier (only other offer in the last month was misty skull fruit shoot), so setting 7.5 as the high end.
