The trade happened quickly before bp.tf could update the item history, so I took screenshots instead:

Yesterday I bought the hat for 16 keys, and then later today I sold it for 18 keys. Few of this hat are in existence, and this one was just recently unboxed a week ago. Buy orders are higher than the price so it needs an update. I checked the other ones that were used in previous price suggestion but they've stayed in backpacks for a while, so I don't think that there's any recent sales with item histories but if there are lmk and I'll factor them in.

Not very experienced with price suggestions so let me know if there's anything else I need to do

Edit: Oh yeah here's the hat that was used: https://backpack.tf/item/9788125598
