I love this hat and recently sold mine for a good price, I've also noticed that when I tried to buy one there were tons of offers about for higher than the current price

Decent amount of demand in this item too.

Proof 1

Proof 4

My trade

sold it for a planets liquidators lid which has the value of 1.1 – 1.3 buds

Thanks to the admins for the next 4 proofs.

Proof 5

http://www.tf2outpost.com/trade/13769435  1 bud b/o

Proof 6

http://www.tf2outpost.com/user/287185  your offer in link one got one it seems

Proof 7

http://www.tf2outpost.com/trade/13506786  b/o of 25. sold for 1 bud? 

Proof 8

http://www.tf2outpost.com/trade/13714355  sold for (atleast) 22 keys?

Conclusion

the item's lowest value has not shown to be offered here so 21 keys should be removed from the range but 22 keys would be a safe low range.

For the higher range I think a rise In price will be possible to about 1.1 earbuds.

So with this proof I suggest that the new value is 1 - 1.1 buds to be somewhat better

As normal, feedback and constructive criticism welcome!
