Conclusion: Before you say something stupid like "Not enough proof, downvote", take a look on the market first. This thing is so rare now. Demand > Supply because supply of craft hats went down and it's reasonable for this thing to rise. There is no other sale at 1.33 so 1.33 shouldn't be in the range.

Feel free to counter / support my proofs.
