A collectible card game (CCG), also called a trading card game (TCG) among other names, is a type of card game that mixes strategic deck building elements with features of trading cards. Cards in CCGs are specially designed sets of playing cards. Each card represents an element of the theme and rules of the game, and each can fall in categories such as creatures, enhancements, events, resources, and locations. All cards within the CCG typically share the same common backside art, while the front has a combination of proprietary artwork or images to embellish the card along with instructions for the game and flavor text. CCGs are typically themed around fantasy or science fiction genres, and have also included horror themes, cartoons, and sports, and may include licensed intellectual properties.
The value of a CCG card depends on a combination of the popularity of the game, the popularity of the intellectual property on which the card is based, the card's condition, the scarcity of the card, whether the card has an artist's signature, and the gameplay value (power or efficiency) of the card. In some cases, the cards have become collector's items of considerable value. Most of the priciest cards come from the first CCG, ', or from some of the other most popular CCGs such as Pokémon or Yu-Gi-Oh!.
This list only contains cards actually sold, not estimated prices of unsold cards, at a price of US$300,000 or more.
The list is ordered by default by original sale price but can be re-sorted by consumer price index inflation-adjusted value (in bold) in United States dollars in .
Cards are evaluated by third-party services, most often Professional Sports Authenticator (PSA), Certified Guaranty Company (CGC), Beckett Grading Services (BGS), or Sportscard Guaranty Corporation (SGC), and given a grade on a 10-point scale based on condition.
The population column is the number of copies of the card in the original print run, not the number of known surviving copies in the present or of the graded quality.
