Although technically only 171k matches, fairly certain rest of the stuff buyer qs the same day to Quicksell.store ended up in this trade, enough value to reach the listed B/O at 180k

Hmm, not sure if I am confident calling the 180 sale 180. There is no plausible items in the obtained section of Apex's compare that the 9 keys could of been spent on, plus there is a key in the obtained together for the qs store bot, meaning the items were likely sold for some other item, which may or may not of been added to the trade https://backpack.tf/profiles/76561198850178158#!/compare/1635206400/1635292800

I would go 175 flat (rounded) off the new sale; the 180 sale might be 171 but I would rather use it as supportive since there is a good chance that it is not 171.
