Do toy story exclusive plush toys increase in value?

The sources supplied do not contain any data concerning the market performance or value appreciation of Toy Story exclusive plush toys. Mattel, the manufacturer mentioned, is a major toy producer but the Wikipedia excerpt only discusses its size and product lines, not the resale or collectible aspects of specific plush items. Likewise, the knowledge graph confirms the existence of the Toy Story franchise but provides no details on the pricing or collector value of exclusive plush variants. Consequently, there is no basis in the evidence to assert that these plush toys increase in value over time. Observations about collectible toy markets are outside the scope of the verified information given.
