Second sale looks like quicksell,imo.

There were Two buyer at 105~110keys(mixed) (They contacted me and second seller.) and second seller(unboxer) was selling for 85keys.

The second seller just started to sell and then turned it on to Buy order.(There were buy order at 75. Burning and scorching both. I have proof about this)

Second sale was indeed to a buyer: http://www.tf2outpost.com/trade/29350467

Was not to an actual quickbuyer however, so that doesn't specifically support the narrative that 75 is a quicksell price. Basically we have two sales here with no current sellers and no clearly defined outliers. Both sales are heavily pure. For an unpriced hat like this one, it makes the most sense to include both and accept a rather wide range.
