Take a look at how the Fast Learner acted when it got released in a crate :P These are way more common, I was predicting them to drop to craft hat price just to that. Oh well, proof says what price is, may drop later.

I agree, it's looks appeal to me too. The new crate having this may have brought it new attention, so people that were in the market for a soldier hat see this and think it looks cool, so they buy it for a higher price.
