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 4

My trade

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

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 took some time to consider this as the price I got mine sold at was “unusually” higher than normal for this I will not make it the top range of the value however I think It would be safe at 27 or 28 keys

So with this proof I suggest that the new value is 22 – 28 keys or 1 - 1.2 buds to be somewhat better

As normal, feedback and constructive criticism welcome!
