Do toy story action figures appreciate in value over time?

The only verified information available identifies the entity "Toy Story" as a known movie. No source in the provided evidence discusses toy figures, their production, sales, or market trends. Consequently, we cannot confirm whether Toy Story action figures increase or decrease in value over time. Any assertion about appreciation would be speculative and not grounded in the supplied data. Further research, such as consulting auction records or collector marketplaces, would be required to answer the question reliably.
