The 300 seller is a QUICKSELL for pure only, and it is poorly bumped, with the trade being inactive for around half of the time it's been up for.

Secondly, the bulk sale isnt what it was sold for. It was sold for a magnetic space mann + orb fire cardbeard (prices were updated around the time of this sale, making those two items that were traded for the exe worth roughly 475-500) http://backpack.tf/profiles/76561198131994315#!/compare/1481155200/1482105600

I have more sales that would further disprove your value.

1. I sold this hat for a magnetic space mann + electric space mann + orb fire cardbeard (prices were updated around a week after this, valuing this sale at 575-600) [this sale is around 2 months old, though, but it still does fall within the past 3 months.] http://backpack.tf/profiles/76561198131994315#!/compare/1480723200/1481155200

2. [~1.5 months old] Secret Exe (=X) + Spectral swirl (=62) + sweets (=8) =x+70 [x being the value of the secret exe], sold for secret vintage tyrolean (~200) + miami shaman (~150) +CPS well-rounded rifleman (~145) + max's head (~19.5) = ~514.5 https://backpack.tf/profiles/76561198073872845#!/compare/1481846400/1481932800

514.5=X+70

x (Value of secret executioner) = 444.5

*Yes I'm aware I didn't use updated prices on the hats in sale two in my further evidence, however, my point that this value of 300 is too low still stands*

As a final note all of my sales are within the past 3 months here.

You have one piece of evidence that supports your value, whereas over the past few months I have multiple that would say otherwise. In terms of pricing relative to other high tier effects, somewhere around the current price is where the price of this hat should remain.

If you wanted to update the price on this hat, you would likely half to go and do a bunch of minis on the hats in the sales I have provided, and the price that you would find after taking into account my sales would likely be significantly higher.
