Most of us have those one or two items in our collections that are priceless treasures (at least to us!) -- but how many of you all collect something that's absolutely worthless? I'm talking about crap that's probably not worth the shelf space it's taking up, but you keep on buying it/them!

I love buying old computer software, especially C64 and PC games that I used to own. Even when I find them on the cheap, I know that they're probably not worth anything. I recently picked up a copy of Space Invaders for the PC (a Windows 95 release) for a couple of bucks, and at the time I remember thinking "that's probably a couple of bucks too much."

Is there anything you collect that has no financial value what-so-ever?
