How do collectors verify the authenticity of a toy story action figure?

The available source material concerns Kenner Star Wars action figures and does not provide details about Toy Story figures or authentication practices. Because no evidence exists in the provided references regarding Toy Story action figures, it is not possible to describe specific methods such as packaging analysis, serial number checks, or material composition. Collectors generally rely on reputable dealers, certification, and comparison with known genuine examples, but without documented sources for Toy Story, these remain unverified statements. Therefore, any claim about authenticity verification for Toy Story action figures would be speculative.
