Which disney characters are most traded as pins at disney parks?

The Wikipedia article on Disney Experiences focuses on the corporate structure, history, and scale of Disney Parks as a business division. It details that Disney Parks is the world's most visited theme park company with over 157.3 million guests and approximately 130,000 employees as of 2015. The article covers organizational changes, including the merger of Disney Consumer Products and Interactive Media into Parks, Experiences and Products in 2018. However, there is no mention of Disney pin trading culture, character popularity metrics, or trading statistics that would indicate which characters are most commonly traded among guests. To answer this question accurately, evidence would need to include specific data about pin trading trends, character popularity rankings, or Disney trading community reports.
