Only recent sale, last one was by Future (aka Josh).

The keys aren't showing in my backpack comparison, I suppose this is because I acquired them on marketplace the same day.

You can also see my trade history here (although I couldn't fit all the keys in this image; if there's another way to show proof lmk): https://imgur.com/a/l7aZgGo

The hat description should be visible in the first image, the second one highlights Future's profile so that the ids can be verified (see bottom left). You may have to zoom into the images a bit since the text is pretty small lol
