How do i verify authenticity of disney exclusive toy story toys?

The evidence I have only confirms that Toy Story is a Disney and Pixar property and that Disney produced an interactive storybook series in the 1990s. It does not contain any details about the production, certification, or authentication processes for Disney exclusive Toy Story toys. Therefore I cannot provide a reliable method for verifying authenticity based on the sources available. If you need guidance, you might consult official Disney retail sites, licensed distributors, or reputable toy collectors’ forums for criteria such as manufacturer markings, packaging, and serial numbers.
