After further discussion in this suggestion (https://backpack.tf/suggestion/648d156d6fab0aa4740aa5c0#comment-64bd6afe268835db4a03c087) , a price range of 115-200 keys has been decided more preferable rather than straight up putting a value of 200 keys :

$200 sale here requested to another user by me here : https://mannco.store/item/440-scorching-flames-unusual-starlight-sorcerer

And then traded away directly to me : https://imgur.com/a/KtO460y (sales are linked)

Miami Nights HKC has price range of around 120, so that'd be ~120 + 5 = 125 keys

200, 116, (115), 184, 115, 125, (160)
