When purchasing Disney Action Figures, there are two approaches you can take.
You can purchase it to play with, or...
You can purchase it to collect
In this article I would like to take a look at collecting. Although there are no guarantees on what will be considered a collector's item in the the future, you can at least try and be selective in what you invest in. I think it is safe to say that Toy Story 3 has solidified the Toy Story franchise as Disney's most successful animated franchise ever, at least for now. Many Toy Story Disney figures are highly likely to become collectibles. But which ones do you choose? The are so many out there, and most will probably fall well shy of collectible status.
In my opinion you should start with the official Disney / Pixar TS3 Toy Story Collection. These Disney figures can be identified by the inclusion of a Toy Story Collection certificate of authenticity. This collection also tends to have a bit more detail, which also plays a great deal into the collectible status probability. Although many websites may vary the figures name description a bit, most should tell you in the actual item description if a particular action figure comes with the certificate.
Now I must leave you with a final warning, especially if you are new to Disney Figures collecting. If you happen to have children and you decide to invest in a few of these Disney action figures, you may want to embrace both of the aforementioned approaches. If you do not, then be prepared to have a really good hiding place lest you be accused of being unusually cruel. As fun as these toys are to collect, lets be honest, they are even more fun to play with. Just something to consider. Happy collecting.
