as for me,i collect:

ceiling fans
christmas decorations
clocks
radios

I don't collect much of anything. I do have 4 ceiling fans in the house but that's only to keep cool with. A few Bonzai trees but probably ones a serious collector would scoff at but I enjoy them. By in large I would say my wife is a collector (of everything) and I am a closet trasher.

Let's see..........

I collect and build models
I have a collection of diecast cars
I'm a woodworker so I have more tools than a lot of people, but I really prize my old wood working tools.
I've recently discovered the joy of cooking with cast iron, so that collection is just starting out.

If money were no object ...............I'd have a whole lot more that I collect.

I am not really a collector of anything. But if having to chose it would be guns and knives I have more of them than anything else. Course if its old I like it. I used to collect old bottles but gave them away. CF:)

I collect Alaska Native art. And cookbooks- though I think of that sadly as more of an addiction than simple "collecting". Hee-Hee!
