The problem I see it as someone who hates trying to time markets is that the market for this stuff is very fickle. Some hit a nerve with collectors and become $500, $1000 books, but many do not and you risk paying decent coin for something that settles down to $15 or whatever. If your goal is to not lose money you need to watch this stuff lime a hawk and it can be stress. More established, vintage stuff, not as much, but there are flavors of the month there too. Unless whatever movie is a huge success I don't see Eternals 1, for example, maintaining its current status. We've already seen MS. Marvel slide. So even older stuff is not immune. With that said, whoever paid $15 for this variant when it came out did alright, for example (ok. Not a signed limited)
