https://backpack.tf/profiles/76561199581722058#!/compare/1781222400/1781308800 - Added 27 Keys for a Purple Energy Sophisticated Smoker

https://backpack.tf/profiles/76561198178279867#!/compare/1781395200/1782172800 - 65 Keys

The Sophisticated Smoker has buy orders at 92 Keys now, so that sale is 65 Keys minimum, and it has a Marketplace sale ~127 Keys. The Tavish sale is similarly 75 Keys minimum. With the series of dumps for less, taking the 65 Key sale (even if that now matches the buy order price for the Rifleman) would be best as a mini.

The Stickybomb Launcher in the sale for item 9 sold for $69.99 (37 Keys)

https://marketplace.tf/items/tf2/207;11;w1;pk407;kt-3

However, with what the seller had originally paid, they dumped the Mohawk for a fair bit less, so that sale can be excluded.

Your 167 sale is 166 + 1 Refined. 220 Keys is high compared to all the other sales, so 166 - 185 would work here.
