Pin to buy this year??

[MonoManBlue]

What are the rarer/limited edition pins that everyone is on the lookout for this year? Do they still sell any of those with a small piece of the attraction? What are THE pins to buy this year??

I want the ones that will become more collectible down the road.

 

[Cheshire Figment]

The ones where the edition size is 500 or fewer and already sold out.
