Most collectors consider having one of each of the 520 cards a complete set. Most will not be able to collect every front/back combination, but will instead include a sample of each back with their set.
Of course some collectors have obtained all 523 (even 524), but that is beyond most budgets. And there are a few on this board who do try to collect all the front/back combinations, but most of them started this project many years ago when these cards were more accessible and a lot more affordable. Starting a master set today would be a daunting task.
