You need at least two sales.

First of all you need 2 sales, which you don't have

Second of all if there are 2 people selling for 1.5 and 2 how can there be 2.3 in range? it is most likely an outlier

And for my last note, Scorching Copper original price is 2.6 - 3.2, ~2.6 after overpay

BUT there are currently 2 at classifieds, 1 for 2.5 and 1 for 47 keys (~2.5)

So if there are 2 for 2.5 in classifieds price is obviously outdated

Anyways no sales, sellers below offer which is probably outdated

As indicated, all suggestions for new hats require two sales to establish a range.
