buyers at 40 keys and 37 keys, so I will go off of 44 key pure sales as new price, considering 40 keys are quick buys.

Edit: addition from marty birdman

https://backpack.tf/profiles/76561198021055079#!/compare/1518912000/1518998400 - Peace Truckers (indate, 39), Blizzy Engineers (mini at 15), Screaming Jumping Jack (buyers at 8/9, just taking that, since...) 39 + 15 + 8 = 62

http://www.tf2outpost.com/trade/29520456 - B/O was 55, caps there

Engineer mini:

https://backpack.tf/profiles/76561198199729741#!/compare/1515283200/1515369600 - 12 pure + 2.5k sweets, ~15

Other new Cone sales:

https://marketplace.tf/items/435;5;u13 - ~35 (countered by buyers) & ~61 (countered by multiple current sellers @55, but supports including a high end)

Some notes about your sales:

Sale #7 was a C9 Metal Slug (outdated, mini at 14), KaW Powdered (outdated, mini at 19), and O. Fire Warhood (18.5). The hats you mentioned were involved in a second sale between the same two traders for a Steaming Villain's Veil. ID#s identify which hats were involved in which sale.

19 + 14 + 18.5 = ~52, maybe a bit lower with a Powdered sale, but not much

Slug mini:

https://backpack.tf/profiles/76561198066195760#!/compare/1518912000/1518998400 - 14 pure

Powdered mini:

Some of your other sales, such as sale #3 and sale #5 (can be used for the TC) look like they would fit within the range of the other sales we can place a solid value on (44, 52, 55).

Looks to me like 44-55 would be best here. Sale #9 looks like a qs, but sale #1 took a while. Can keep that as a low end.
