There’s more to unusuals than bot.tf. People are quickbuying this hat for 33 keys, that is not a usable data point. You have to look at item histories and backpack compare links and determine what they have sold for and create a price range using the sales you find.

If you are looking for help, I would suggest you to try looking at some other experienced suggesters, look at some guides under the backpack.tf rules, or ask on the backpack.tf discord.
