Purple energy elf esteem is like 15k

Green energy blast defence doesn't have recent sales outside of Mannco.store so i'll have to go with the april one which is of 118k which seems to have remained relevant

https://www.backpack.tf/stats/Unusual/Blast%20Defense/Tradable/Craftable/9

They were traded for the Roboactive Strontium Stove Pipe and a Specialized Killstreak Australium Sticky Launcher https://www.backpack.tf/stats/Strange/Australium%20Specialized%20Killstreak%20Stickybomb%20Launcher/Tradable/Craftable

which is around 22k

118+15-22=111k

Death at Dusk Prince Tavish's Crown was recently priced at 295k: https://www.backpack.tf/stats/Unusual/Prince%20Tavish's%20Crown/Tradable/Craftable/90

Iridescence Brim of Fire as well has a 4 months old price suggestion at 62k, but 2 of them were dumped on November for approx 55 keys

https://gladiator.tf/sales?item=Iridescence%20Brim%20of%20Fire

in addition one was sold on MP on October for 118usd which is around 65k: https://marketplace.tf/items/tf2/31185;5;u188

average price: 58k

Death's Daggers Mr. Rostov: recently priced for 155k https://www.backpack.tf/stats/Unusual/Mr.%20Rostov/Tradable/Craftable/376

total: 508k at which will be subtracted:

12 keys

Roboactive Respectless Rubber Glove that has no recent sales whatsoever so i'll just go with rule of thumb:

B\O's at 153k and it's currently selling on MP for 264k and has been listed there for a month, so i'll go with -15k every 2 weeks:

204k

Roboactive Dread Knot that has a 6 months old price suggestion but that won't do, so since it lacks recent sales i'll have to go with rule of thumb again:

B\O's at 63k and 2 listings at 175k, one was listed for 2 months, i'll go with -5 keys every 2 weeks so 135k

So for the Roboactive Strontium Stove Pipe: 508-12-204-135= 157k

Average price for the Roboactive Strontium Stove Pipe: 134k

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

So the 2 hats have a value of 186k

they were traded in exchange of the Anti-Freeze FR-0 and 15k

Iridescence Wild Brim Slouch: this one is tricky,, no sales data in the past 4 months, one has been selling for 20 keys for a month and B\O's are at 11,71k so i guess im allowed to drop this down to 15k, at least that's what i red in the rules of unusual price suggesting.

https://backpack.tf/stats/Unusual/Wild%20Brim%20Slouch/Tradable/Craftable/188

Galactic Gateway Mann-O-War https://backpack.tf/stats/Unusual/Mann-O-War/Tradable/Craftable/114

sold by a bot on October 15th for 48k: https://gladiator.tf/sales?item=Galactic%20Gateway%20Mann-O-War

but it's now selling for 44k so i guess i'll just roll with that

3rd trade on December 6: https://imgur.com/a/Zoq5iGa

my trade: the hat alone in exange for:

16 keys

VFB Graybanns no specific buy orders, lowest listed are 49k: https://backpack.tf/classifieds?item=Graybanns&quality=6&tradable=1&craftable=1&australium=-1&killstreak_tier=0&spell=Voices%20from%20Below

Conga taunt (3 keys): https://backpack.tf/stats/Unique/Taunt%3A%20Conga/Tradable/Craftable

Gunslinger pro kit FH+HR, the combo is worth some overpay but it's pretty arbitrary so i'll go with 7k:

https://backpack.tf/stats/Unique/Killstreak%20Kit/Tradable/Non-Craftable/3-142

Burning Flames Trucker's Topper has a recent price suggestion at 99k but it's currently selling for 90k, so i'll go with that https://backpack.tf/stats/Unusual/Trucker%27s%20Topper/Tradable/Craftable/13

price: 90+7+3+49+16= circa 165k

final price: (171+203+165)/3 = 179k

this took me an entire day, now i know why old hats are not price suggested

big thanks to all the traders that provided me with the screenshots
