Sale 1:

https://backpack.tf/profiles/76561198402732959#!/compare/1530057600/1531008000 (buyers bp)

It was bought for a Strange Professional Killstreak Festive Medi Gun (+4 keys) when I tried to trace it down, what it was sold for, no evidence showed up

neither in the seller's nor in the buyer's BP (buyer was a BOT, checked nearly all key histories + stranges, but nothing)

So I'll be using SCM to actually give a price to that mini. so we have 3 sales in the nearest past I'd use, which are 47,31€ (31st of Aug), 47.32€ (1st of Sep) and 47.58€ (4th of Sep) (not taking the 51,91€ sale, it'd be too high) 47,31+47,32+47,58=142,21/3=47.4€ ||| keys were sold mostly at the price of 2,09€ on 31st of Aug, 2,08€ on 1st of Sep and 2,06€ on 4th of Sep = 2.076€ on average so taking it as 2,08€ ->>> 47.4/2.08= 22.78 -> 23 keys

So the mini would be 23 keys here minus the 4 keys

19 keys

(lmao ima kill myself if it wont pass)

Sale 2:

Sale 3:

https://backpack.tf/profiles/76561198305676157#!/compare/1534377600/1534636800 Sold for a PE Larrikin with 5 keys, open sugg for PE larrikin @ 26.5 Given the fact that there is an unsold one at 20 keys, I'd round it down to 26 keys - 5 = 21 just to be closer

Going with 19-21 range.

Not a lot of sales, but that's the best I could have done, hope it'll be fine.
