We can probably agree that for every collector a sense of achievement is a powerful motivator. However, the way we find that feeling of success can vary. Perhaps it’s when you save up enough money to buy that super rare Pikachu Illustrator Card or when you finally complete your collection of Disney movies on VHS. Whatever it is that motivates you, one of the biggest honors a collector can achieve is recognition from Guinness World Records. These five collectors found their sense of achievement by breaking records for the biggest collections in the world. See what it takes to accomplish this feat!
