The Phantom is outdated, and this taunt has many other recent sales. The Killer's is a good sale, but there's no mini for the Phantom. I think that the Phantom trade should be used to price the Phantom rather than this. Gotta downvote.

Mini for CM - http://www.tf2outpost.com/trade/28353307 - sold for over the b/o of 125. Other hats don't really have minis but shouldn't affect the price much

http://backpack.tf/profiles/76561198068309144#!/compare/1471564800/1472428800 - capped at the b/o of 230 - doesn't matter some of these are outdated because in unusuals this is well over 250 - http://www.tf2outpost.com/trade/28432266

I think 175 is an outlier here with sales at 210, 230, 230.

EDIT: Found another one to support the low end here - http://backpack.tf/profiles/76561198070143554#!/compare/1472947200/1473033600

Wide range is probably okay.
