How to verify authenticity of a toy story action figure?

The only evidence provided pertains to Kenner Star Wars action figures, describing their production, sales, and auction prices, and does not address Toy Story or its action figures. Because there is no documented information in the supplied sources about Toy Story action figures or their authentication methods, we cannot offer specific guidance. An accurate answer would require additional reliable references that discuss Toy Story merchandise, manufacturer details, or collector guidelines. Without such evidence, any advice would be speculative and therefore omitted.
