I was who told you to round up to 100, but eh, i just get a dislike.

Eh, I dunno about this one.

Another sale:

Sold + miami noble [outdated 32] and 20 keys for a PE cannonball (~115)

That's significantly lower than this

its probably low since he was actively using for a HCB

but before that, he had been selling for over a month at 90:

Theres also a fairly old trade for a scorching geisha + 20 keys

http://backpack.tf/profiles/76561198085956941#!/compare/1455955200/1456041600

Geisha is just outdated, and has a seller at 55, at which that sale would be 75.

Due to that seller for 90 for a while, I feel like this'll need a range at least. The cannonball sale will be ~60 but as said, thats probably low since the seller was actively looking for that cannon, and likely overpaid for it.

Id personally want to see another sale to see if 100 is an outlier or not
