I’m not able to verify that from the information available here, so I can’t give a reliable count. The phrase “more than 1 hat” could mean teams with multiple cap styles, alternate hats, or just people collecting more than one team cap, and those lead to very different answers.

What it could mean

  • MLB teams with multiple official cap designs : almost certainly many teams.
  • Teams with more than one hat in a fan collection : impossible to count without a specific collection or dataset.
  • Teams wearing special hats for an event : that depends on the event and season.

Best interpretation

If you mean MLB teams that have more than one official hat design , then the answer is effectively most or all teams , since clubs commonly have home, road, alternate, and special-event caps.

Why this is fuzzy

“Hat” is not a standard baseball statistic, so there isn’t one universal count. The wording needs either:

  1. a specific league, or
  2. a specific meaning of “more than 1 hat.”

Here’s a cleaner version of the question: “How many MLB teams have multiple official cap designs?”
