Welcome to Subeta dear, I'm going to let you keep this thread here as you're barely over the month limit :9 SubetaLodge is a great item database site (see below links) that can help you look up things.

Some items are super expensive because of their rarity, and they still sell for that much because there are things in the site (like advanced levels of the Item Hunt game) that ask for retired/super rare items, or maybe just some crazy collectors :)

I think that's everything so far answered? Feel free to keep asking if you're not sure of anything still c:
