Some of my favorite pins to collect are Hidden Mickeys. These pins are first released to cast members to trade with guests, but are then released in mystery bags. The series are always super creative and fun! My favorites are anything involving signs in the parks. For example, the old Matterhorn loading sign was turned into a pin and the most recent HM series at Disneyland featured restroom signs from around the park.
There is usually a shared series that both parks have and then a few series that are exclusive to each park. Some of the series are the same, but have different designs for each park collection. I tend to love the more creative ones that focus on minimalist design or wink at some fun Disney history.
