What factors influence the rarity of toy story collectibles?

Quick Answer
The rarity of Toy Story collectibles is generally determined by how many were produced, how many survive in good condition, and how much demand collectors have for them.
Explanation
Rarity in any collection, including Toy Story merchandise, arises from a combination of production quantity, age, and condition. Items that were manufactured in limited runs or discontinued early tend to be harder to find. Additionally, pieces that remain in excellent condition or have survived over time are more valuable to collectors. Demand also plays a role; highly sought-after characters or versions can elevate an item's rarity even if it was produced in larger numbers. Because the available evidence only describes the general practices of collecting, these principles are applied broadly across all collectible categories without specific data on Toy Story items.
