Rarest Items on AJ?

Hey Jammers! I've gotten this question many times before: What IS the rarest item on AJ?

So far I have been seeing the same things over and over, that a lot of Jammers have already! Tops were pretty rare, until they came out. I personally think, from polls and asking friends, or Jammers that these two types of items are possibly the rarest right now. What do you think?

Pink beard/ or other uncommon beards.

and....
