How do i determine if a toy story exclusive is authentic?

The only verified evidence available identifies Toy Story as a known entity but offers no details about merchandise, exclusives, or authenticity checks. Because no source in the provided data addresses the topic, we cannot cite any specific criteria or procedures. Generally, to determine authenticity of a collectible, one would consult official publishers, reputable retailers, or licensed distributors, and look for packaging, serial numbers, and manufacturer marks. However, without explicit evidence from the sources given, we cannot confirm that these methods apply to Toy Story exclusives or recommend any particular brand or verification process. Therefore, any advice on authenticity would need to be sourced from external reliable references.
