Might be a third gen effect but Shamans are rarely unboxed. Two C9 Shamans exist but the other is gifted so for all intents and purposes this hat is 1 of 1 and is very likely to stay that way.

Sold for the following items; total value = ~9.5, outlier... T_T so many suggestions for nothing...

Phosphorous Flippled Trilby (~3 see http://backpack.tf/vote/id/53d50b5c4dd7b8a73b8b4568 )

Phosphorous Tough Guy Toque ( ~1.3 see http://backpack.tf/vote/id/53d5187e4dd7b8c97e8b4568 )

Circling Hearts Prince Tavish's Crown (~2.9 see http://backpack.tf/vote/id/53d510cf4dd7b8740c8b4568 )

Disco Beat Down Titanium Tyrolean (~2.3, yay for not needing a suggestion...)

Sold for the following items; total value = ~23.1, definite outlier

Circling Hearts Combustible Kabuto (~9.7, see mini)

Terror-Watt Crone's Dome (~11.7)

Haunted Ghosts Rimmed Raincatcher (~1.7 but 10 months outdated. Pretty clear the whole sale is an outlier so no mini is coming)

Mini for Kabuto, if I could conclusively say the hat hasn't just been swapped between alts then I'd count the other trades and make a full suggestion

Sold for Arcana Marauder(~4.7) and a Spellbound Soldered Sensei (~6.1) = ~10.8

Mini for Crones: too lazy to look for another sale on what is clearly going to be an outlier anyways

Sold for 13 buds
