People who collect the Pokémon cards also want to know which cards are worth money. The answer is a combination of rarity, condition, and the edition of the card. Some of the most expensive cards released include the First Edition Charizard, Pikachu Illustrator card, and rare trophy cards. Holographic cards released in the early days, along with cards that have been graded by PSA, also rank amongst the most valuable Pokémon cards.
