How to verify authenticity of disney world toy story collectibles?

The only facts available to me come from a knowledge graph that confirms the existence of the Toy Story franchise and from a Wikipedia article about Disney’s Animated Storybook, a point‑and‑click game series. Neither source discusses physical merchandise, collectibles, or methods for determining authenticity. Therefore, based solely on the given evidence, I cannot provide a reliable guide for verifying the authenticity of Toy Story collectibles. If you need detailed verification steps, you would need to consult additional sources such as official Disney merchandise guidelines, reputable collector communities, or authentication services that specialize in Disney or Pixar collectibles. Until such evidence is provided, any advice would be speculative and potentially misleading.
