Sale #4:

https://backpack.tf/profiles/76561198144022966#!/compare/1707091200/1707350400 ~ sold for 40 keys + some ref (below buyers)

Sale #5:

https://backpack.tf/profiles/76561198059382847#!/compare/1708732800/1708819200 ~ ??

Sale #6:

https://backpack.tf/profiles/76561198000426108#!/compare/1708560000/1708646400 ~ potentially 58 keys? the keys dont match though. The buyers backpack is hardly refreshed/update so it is possible they are just not in the history.

Sale #7:

https://backpack.tf/profiles/76561198389596775#!/compare/1707782400/1707868800 ~ added 30 keys for a peace sign HKC

Mini HKC:

https://marketplace.tf/items/tf2/30177;5;u18 ~ only sale I can find is marketplace.tf, $143.99 / 1.7 = 85 keys (unsold seller at 80, but they also say they will take 72 keys). So if we cap this at 73 keys - 30 = 43? Best to ignore this sale? seems like an outlier compared to our other sales anyway.

Sale #8:

https://backpack.tf/profiles/76561198358422068#!/compare/1702425600/1704758400 ~ cash maybe ? Sold bp?

Sale #11:

https://backpack.tf/profiles/76561198248511368#!/compare/1701993600/1702252800 ~ 30 keys? (im assuming 40 keys using gladiator.tf, either way under buyers now)

Sale #12:

https://backpack.tf/item/13650677030 ~ gambled every single time aaa

Sales (ignoring those below buyers):

49, 49, 49, 57, (maybe 58?), 59, 60, 60, 60, 60, 71, 71, 71, 71, 75, 83

Two unsold sellers at 60 (11 days and 4 days) https://i.imgur.com/qZCmfsu.png + 1 seller at 54.49 keys (new seller only a couple hours old)

So going to ignore the above 60 sales and take 49 and 60.
