If you were buying Happy Meals during McDonald’s Pokemon collaboration, you may have something more valuable than just a kid’s meal. The collectible Pokemon cards that come with Happy Meals have been getting bought up by collectors and scalpers and selling big on eBay. A single Pikachu card from the collection reportedly sold on eBay for $500! Of course, since scalpers are buying and selling these cards at high volume, it may be harder to get your hands on your own Pokemon cards. Have you ever collected anything to sell online? What was your favorite Happy Meal toy growing up?
