With the signed items, someone can view your item tooltip in a match and see a big ol signature and that's enough to add a little cosmetic value, like you said. The different grades of rarity can also be viewed, but IIRC it's only a word added before an item's name so you don't really get anything out of it.

The dude who got his Bored Ape NFTs stolen has nothing to display to the public to prove he has them or not. It's literally just the same image file as everyone else can get, if I understand the concept.
