It's still 1 of 8, and a god tier unusual effect on a god tier all class hat. And having a "best offer" of $900 does not mean the hat is necessarily worth that much, just no one is able to top the offer (yet) heck those trades have been open for 1 week, offers don't come that quickly. Most god tier hats (like this one) take a good month to sell for it's actual value.

I wont mention what price I think this hat is/should be since I own one and that is considered "price manipulation" but all I gotta say is that 35-45 buds as a suggested price is not a fair value, the 45 is alright, but heck if anyone is selling this for anything near 35 I will buy it immediately, hit me up!

Also, you mentioned 2/4 on the market, of the 8 hats in existance. In such a tight market, If these 2 trades are able to sway the price towards 35-45 (from 40-52) then what about these 2 trades?

The first is mine, lets ignore this because its considered "price manipulation." Plus its only been a day that that trade is open.

The second being Ambidextrous, where he has multiple unusual offers of 40+ buds. Note its been open for only 1 week.
