What are the most sought after exclusive toy story collectibles?

The provided sources discuss the Toy Story film itself, its plot, cast, and production background, but they do not mention any exclusive toy or collectible items associated with the franchise. Because there is no documented reference to specific collectibles, it is not possible to list or describe the most sought after exclusive items. In the absence of such evidence, one cannot determine which exclusive Toy Story collectibles are most popular or sought after. If you are looking for information on official merchandise, you may need to consult additional, dedicated sources such as Disney or Pixar merchandise catalogs or fan forums.
