Here's an unusual collection: Various "Do Not Disturb" signs from hotels.
Now, that's an odd thing to collect. I used to collect TV station microphone flags (those little plastic cubes on microphones that show the station's logo). I got four or five and realized that I really didn't care about them, so I sold them on eBay. You'd be surprised at how much people pay for them.
Do you collect something odd?
