The most expensive Pokémon card in the world is the Pikachu Illustrator card. It was originally given as a prize in a 1997 art competition by CoroCoro, and only 39 copies were made. Today, only 10 confirmed copies exist, making it extremely rare and valuable. The card has consistently fetched high prices over the past few years, typically between $375,000 and $6 million. In July 2021, the card sold for a staggering $5.275 million, making it the most expensive Pokémon card ever sold.
