I have a few signed books from various authors, actors and public figures. I have an old Amiga 500+ that still works and which uniquley has the 500 chip in it and a toggle switch to boot up either one. I own a few cool, limited edition coins/stamp sets, though I'm not a collector of either (just have a handful of special ones). I have a lot of comics from the 90s, maybe 2,000+ some of which may be quite valuable. I'm fairly sure at least one 6-issue Star Wars series called "Dark Empire" is.
I have a couple of audio tapes which I doubt could be found now (though I've long since digitised them so I can actually listen to them) which have some personal, sentimental value. I've got a moddable PSP2000 for homebrew purposes which is quite rare to find (as most were un-moddable). I've also got a large amount of Star Wars original comics, figures (sadly opened), books and other collectibles which I had from before Episode I, when I was a fan (I blame Timothy Zahn entirely). As it turns out, Star Wars went from being a very niche, cult, nerdy thing to almost as mainstream as you can get so my collection is probably quite valuable.
Oh and I have some rare Magic cards (played for a while a long, long time ago. Current Magic players can understand the time scale when I say Unlimited had just come out (3rd ed??) and I think Arabian Nights and Legends had just finished their runs. I have a few I suspect are probably quite valuable. Oh and I have 2 Eve Online characters I don't play each with 100mill SPs
