Which card is worth more? (Gem Mint value)
Frequently Asked Questions
How do you determine card values in Card War?▾
Card values are based on estimated PSA 10 (Gem Mint) prices from recent eBay sold listings and major auction houses. Values are updated regularly and reflect real market conditions. Some vintage cards are valued at PSA 7-9 where gem mint copies are extremely rare.
What makes some sports cards more valuable than others?▾
Card value is driven by: player popularity and performance, card rarity (print run, parallels), condition (grade), age (vintage premium), whether it is a rookie card, and the set it belongs to. A Mickey Mantle 1952 Topps is valuable because of all these factors combined — iconic player, vintage age, limited surviving copies, and the most famous set in the hobby.
Why are rookie cards worth more than other cards?▾
Rookie cards are a player's first officially licensed card and serve as the "stock" of that player's career. They capture the most upside — if a rookie becomes a Hall of Famer, the RC appreciates the most. The hobby convention of "rookie card = flagship card" drives demand and liquidity.
Are vintage cards always worth more than modern cards?▾
Not always. While vintage cards have a scarcity premium (fewer survived in good condition), modern cards of elite players can match or exceed vintage values. A PSA 10 2018-19 Prizm Luka Doncic RC ($5,000+) is worth more than many 1960s stars in similar condition. The key factors are player greatness, card condition, and supply.
