What are the most valuable exclusive toy story figures?

The verified information supplied refers only to the character Jessie from the Toy Story franchise, her origins, and her appearances in the films. It does not contain any data about collectible figures, exclusivity, or market value. Without additional sources or explicit listings of toy releases, it is not possible to determine which exclusive Toy Story figures are most valuable. Collectors often refer to limited edition releases from major retailers or conventions, but such details are outside the scope of the provided evidence. Therefore, based solely on the available information, a definitive answer cannot be given.
