Also, I'm gonna try to start pricing all of the unpriced Unusual Mongolians, starting with this sluggish Robo effect.

All of the proof in this suggestion does come from duped hats, as I couldn't find any clean ones. However, I doubt being duped matters all that much for a cancer tier like this.

http://www.tf2outpost.com/trade/19816531 - Purchased for an Australium Black Box. The hat was offered, so no overpay is applied to either side (1.2 buds, or 20 keys).

http://www.tf2outpost.com/trade/19816531 - Sold for a Smoking Jumper's Jeepcap (.9 buds [w/ buds priced at 17-18 keys] = 15.75 rounded to 16 keys).

http://www.tf2outpost.com/trade/19695276 - Purchased + Orbiting Planets Large Luchadore for a Demonflame FR-0 (unpriced).

http://www.tf2outpost.com/trade/19590671 - Also sold with the Luchadore (1.6 * 0.9 = 1.44 rounded to 1.4) for a Cloud 9 Fruit Shoot (2 * 0.9 = 1.8). Definitely an outlier.
