Only 3 versions of this hat have been traded in the last 2 years (https://backpack.tf/item/1047163112, https://backpack.tf/item/1031722931, https://backpack.tf/item/1048759610)

Purchase for 115 pure almost exactly 3 months ago: https://backpack.tf/profiles/76561198117542709#!/compare/1622419200/1622505600

Purchased for 140 pure last week: https://backpack.tf/profiles/76561198286257338#!/compare/1628380800/1628467200

Sold for 130 pure the week before: https://backpack.tf/profiles/76561198140565712#!/compare/1628294400/1628380800

Sale for 225 pure to me with a spell on it today where I paid around 75 for the spell [so I personally feel I paid 150 for the had itself, but this could easily be an outlier] (as the das was negotiated at 80 pure): https://imgur.com/a/iam6e6I

Had a hard time tracing other sales before quintessiantial had it (2+ moths ago): https://backpack.tf/item/1031722931

Overall this leads us with a pretty much outdated sale of 115 pure, 2 recent sales at 130 and 140 pure, and a debatable sale of 150 pure (which we will ignore for pricing). Overall, that basically leaves us with the 2 sales of 130 and 140 making that the range I believe this item should be price at.

130 to 190 would work.

Combining everything here, I agree with shuffle spy and think 130-190 is fine.
