What is the most rarest figure in your collection?

[advice]

Hi to everybody!

Collecting minifigure is the most interesting hobby for every lego fan. And lots of figures are on wishlist of us we looking up, finding out, trading for.

What's the most rarest minifigure in your collection or wishlist?

As for me, I fancy having Inside tour figures but they are too rare to have. 

And the most rarest I own is Games Staff minifigure and probably black brick on torso the Ideas minifigure

I think this thread already exists elsewhere, maybe worth finding as I think it is quite lengthy. Personally I don't think I have any rare or particularly valuable minifigs maybe the Batman and Joker from the Tumbler set.

Sorry if so but I couldn't find the thread exist.

As for topic do you figures that ain't from regular sets?

I just got known interesting and neat  LEGO Grundlæggende Lederuddannelse 2008 (Basic leader education) minifigure was sold out on ebay. Never heard a thing about it. The figure was only given out to participant who attended an internal program in TLG Billund in 2008.

who knows anything about it?
