McDonald’s has launched a limited-time Pokémon Happy Meal, sending fans of all ages scrambling for their share of the coveted collectible loot — with some heading straight to eBay to resell their hauls for hundreds.

The Pokémon news outlet Pokebeach.com says the four-pack of cards will contain one holo card. These are rare cards that have a holographic, shiny image at the top of the card instead of regular art, and they fetch higher prices in Pokémon trading, according to Moneymade.com.
