To some trading card collectors their sets are not complete unless they have at least one example of the wrapper the cards originally came in. Being that some cards are sold only in factory sets, some cards never had a wrapper to begin with. But if they were available it's entirely possible that finding a prestine example of a wrapper may be a very difficult task. For the most part, especially with the older sets, cards were ripped from the packs and the wrappers destoryed forever. In such cases, the wrapper could be the most valuable part of the set.
