On my main character, Zukeenee, I collect navmaps. Everything (and I mean everything) that can be mapped out or discovered has been found by me on this character. He has also docked on every base that doesn't require an Admin to change your rep for you. Of course, the only thing I'm missing on my map now is Bastille...
On another pair of characters, Tomahn.Gitsah.I and Tomahn.Gitsah.II, I collect Codenames and other high-power fighter/bomber weapons. I don't sell or trade them, I only buy them and store them. I started it as a personal vault, for use when I need to outfit a new fighter or something, but now it's just a hobby.
On my Dacite miner, I have collected one sample of each type of ore found in Sirius, as well as the information from each base that buys it.
