Sellers at 8 and 9 keys. 18 sale is ridiculously high and should be considered an outlier. I also can't find evidence that the TF Logo Guada was actually used in the trade as the items histories don't match up. 12 key sale is yours and uses taunts that may not actually total 12 keys so it holds little weight in raising the value of this hat as there are many more of its exact type in existence.

I notice you have omitted other sales in this suggestion, but to your credit, it has proved difficult to trace them. Can't use sales with scammers and several of the hats haven't moved from their unboxer's backpacks.

I still believe you cannot raise this hat without firm proof of its value being higher. An obvious outlier and your own sale are generally not sufficient to raise a hat of this tier with several in existence, and current sellers directly countering it. Furthermore there is no evidence to support the suggested price of 10 keys, it seems like a completely arbitrary number.

As pointed out above, 10 comes from nowhere and is countered by unsolds. Take a look at this for future reference:
