Suggestion: Sunbeams Globetrotter at 35 keys

Those are the only two sales I am able to track as I don't have premium, so if somebody wants to resuggest with more sales and possibly a range, go for it.

https://backpack.tf/profiles/76561198125789695#!/compare/1614643200/1614729600 - sold for 19 keys + Vintage Specialized Killstreak Gunslinger + 2 spelled hats (going off sellers for the spelled items it looks like this will end up being below buyers)

also your compare for the 35 key sale doesn't show any useful information, here's a better compare from the seller side:

this should be fine
