Proof below. 6 month-old price.

For some reason 1 hat sells for less, can't tell if it's duped though

Sales: 2, 2, 2.8, 2.8, 2.9

2.6-3 should be an ok range. 2.6 is from that one trade which hasn't sold in almost a month (surprisingly) but I can't disprove it. 3 is from an offer. In between are sales 2.8-2.9. Close anyway. 2 is clearly a quicksell and way lower than other sales.
