Tomi- https://steamcommunity.com/market/listings/440/Collector%27s%20Killstreak%20Tomislav?filter=Collectors January 23rd, sold for £25.21, ~15 keys.

Square Dance- https://backpack.tf/profiles/76561198256220348#!/compare/1610496000/1611273600

Bulk. Only sale I could find.

Buyers are ~9.

Puts the caribou at 15+9+2+2=29. Seller at 30 for 8+ days, so this seems fair.

Stickybomb:

1 for 1 with a DBD Team Captain, clean.

TC: https://backpack.tf/profiles/76561198258595884#!/compare/1611187200/1611273600

95 pure.

Veno Shock: Can't find any sales. Buyers are ~7, sellers are 10. I don't believe this would make too much of a difference on a hat of this price.

Total: 95+29+7+10= 141 keys.

Sale 3: Bulk.

Bulk for the Harvest Moon Fedora.

Also seems that PlexoS gave them to Ricky for a period of time, you can see here, he received a bunch of unusuals back off of him which were given a month prior: https://backpack.tf/profiles/76561198348959432#!/compare/1608249600/1608422400

NEW SALE- Sale 4:

https://backpack.tf/profiles/76561198106511423#!/compare/1611878400/1612310400

https://backpack.tf/profiles/76561198053720151#!/compare/1611878400/1611964800

Haunted Phantasm Chieftains and 25 keys pure.

Mini for chieftains:

https://backpack.tf/profiles/76561199063531190#!/compare/1611964800/1612137600

105 pure.

105+25 = 130. Fits within the range.

Overall there are three valid sales.

125 pure, 130 mixed, and ~140 in unusuals.

Granted the guy who paid ~140 in unusuals did sell for 125, but the 125 was pure so I think this should still be okay.

Cheers Blaze:

disco tc has a suggestion up for 95 - 140 keys [Hey that's me!]

https://gladiator.tf/listings/5fff2975622d7436fcbe75d6 - since sale 2 had a b/o of 160 keys this sale should cap at that

given the person who paid 160 keys was the person who sold it to you for 125 keys i would exclude that sale here and go 125 - 130 here

Going with 125 - 130 keys here
