How does rarity affect the price of toy story merchandise?

The only verified fact available confirms the existence of the entity Toy Story. No details about merchandise, rarity, or pricing are present in the evidence. Therefore, we cannot establish any relationship between rarity and price for Toy Story items based on the provided sources. In general, collectors often note that limited availability can influence value, but that is a general observation that is not supported by the current evidence. Without specific data, any statement about pricing relative to rarity would be speculative.
