Sale 6:

299.49/1.84=162.76 ~163 keys

Sale 7:

Sold for $349.99 on January 26 2026

Keys were $1.84

349.99/1.84=190.21 ~190 keys

Sales:

163, 182, 190

Sellers:

BPTF - https://imgur.com/JLuyXUg no current sellers but the buyer at 166 keys has been there for a month

MPTF - https://marketplace.tf/items/tf2/30662;5;u99;strange $399.99 (~213 keys)

STN - can't find the page so they probably don't sell it

SCM - https://steamcommunity.com/market/listings/440/Strange%20Unusual%20A%20Head%20Full%20of%20Hot%20Air?filter=Nebula https://imgur.com/mpTiFPf none

163 looks a bit too low given that buyer at 166 keys was already there when it happened. Going with 182-190 keys
