I don't know what this series of pins are called I just found a strange pattern of Pins :)
Anybody know what the 8/9 Pin is?

4/9 is Adventureland.

Most of them are the buyable pins.

4/9 is Adventureland.

Not anymore... the 4/9 title was dropped a while ago. Now it's just Adventureland Retro, so the final pin in the set seems to be missing for the time being.

Wow.. I was here when it was 4/9 and now the set is forgotten...

Well, the Fantasyland Castle pin no longer says 2/9, either.

Yes it does in the shops :0

Does it say it in your inventory when you buy it?
