I know it's not the best proof but that's the amount i sold it for :)

I think this is more reasonable than your last one for sure. Tons of people buy 1.66 hats for 1.33 from quicksellers, and yet people who actually want this are willing to pay the 1.66. Upvoted, price range is good.

sold one for 1.66 today. I got 2 for 1.33. then again I get a lot of hats as 1.33 quicksells, I'm not convinced these are very easy to find for 1.33 and there are none sitting unsold for that price, so my opinion is that 1.66 is still the usual price for these.
