I move around a bit, and I hate the process of moving. So I routinely prune out the excess in my life, I own very little that's not immediately important to me. Clothing, car, cheap guitar (ha that rhymes), amp, few gaming systems, box of games (which I routinely sell once I lose interest), shelf of books, tv, my portfolio (for employment purposes, I'm not nostalgic at all with my art), drum set (I don't drum but that's one less thing I need in a drummer eh?), laptop, ipod, turn table speakers and record collection, small cactus aaaand that might be...it?
Absolutely hate gifts that serve zero practical purposes and take up much space at all. Because I feel bad getting rid of it.
So yeah, I don't think I've got much of anything in the rarity and/or expensive dept. Maybe a couple of comics, couple of really old first edition books and records.
PS. Most of that stuff is actually still stored in boxes from the last time I moved, which was almost a year ago. So yeah.
