Recently i purchased this unusual from a Auction for 19 keys. This would be i guess the first documented sale of such.

Its the best suggestion i can give since i have proof of purchase and auction link here:

https://scrap.tf/auctions/CHSHSF

3 sales also this year in marketplace that went for 44.99, 17.5 keys approximately

https://marketplace.tf/items/tf2/139;5;u36

Making the value of this items at its lowest 17.5k, also bots are buying for 18.31 keys though, while listings go for 20, if anyone has any proof of it being sold for above 19 keys I think the new price for this should be 17

19-22.5 keys (this is based on 2$usd per key)

I've seen bots buy this for also above 18keys, purchase orders going for 18.31, so clearly this hat at its bear minimum is going for above its suggested value, while listings go for 20 keys at the smallest, market movement suggests that 44.99 usd was paid 3 times for this hat, this May also suggest maybe that the sell that 22.5 is its highest while 19 its lowest, while 3 sales orders are 20.52, 21 and 25.

This range fairly represents the item at its lowest and highest for this year.
