Look, between legacy and guru, there is a long history of threads like this (looking for the rarest item) devolving into "behold my random fascinating crap". I don't think that's the intent of this thread.
In a game like this, which has been around for so long and that has had so many twists and turns in its already complex itemization, there will inevitably be a huge pile of interesting tchotchkes. Others have already made this point (and even in direct response to your post):
many items are "unic" and cool like your's
I think the intent of this thread was to find the pinnacle items in the game. The items that are the best combination of rare and valuable. Items that are, strictly speaking, extremely rare (most likely because nobody bothered to notice them before merching) but not worth anything outside of novelty don't really fit the bill.
In a game with the history and complexity of Guild Wars, a question like the one being asked here should be tough to answer. Or at least it should have a complex answer. But, in reality, I don't think it does. I think the answer is really pretty simple.
The game's tchotchkes are there to be loved and they deserve the love they get. But they aren't the answer. We've tried answering this question that way before and it only leads to an endless sea of doodads and knicknacks. I think this thread (and others before it, if I'm being honest) is aiming higher.
