To the comments with all of you!

To start off there arent alot of trades with the smoking phantom. But I think that there is enough evidence to shorten the range a little bit.

Got an offer within hours which was Hearts stovepipe + 6 keys (2.4)

And later 2 buds + VoT bills (2.4 aswell) Sold for it.

Quite old trade, but semi fresh offers

Stormy Fed Fighting Fedora (2.2)

Orbiting Fire Killers Kabuto 2.1

And about 1 month earlier an offer of vivid milkman + peace trilby (2.8+1.2) I dont know if its real or not.

Lantern Dead cone 3.1 (I dont know if its real or not, I would accept such an overpay in a heartbeat.)

Stormy fed fighting fedora (2.2) Same guy as before

http://www.tf2outpost.com/trade/8278973

All three rejected.

Hearts Conquistador if he adds a bud (3.1-1=2.1)

Orbiting Fire Kabuto 2.1

Stormy Fed Fighting Fedora 2.2

http://www.tf2outpost.com/trade/8269764

Orbiting Fire Handle (0.8) Lowball

Another Stormy Fed Fighting Fedora 2.2

In conclusion this hat gets decent offers, but just doesnt get the high end anymore. I sold mine within a day and a half.
