Frequently Asked Questions
How many cards can I compare at once?
You can compare between 2 and 5 cards simultaneously. Each card is displayed as a column in the comparison table, making it easy to see differences at a glance.
What dimensions are compared?
Cards are compared across 9 dimensions: Sport, Year, Set, Rookie Status, Raw Value, Gem Mint Value, Grade Multiplier (gem/raw ratio), Card Age, and Era classification (Pre-War through Ultra-Modern).
What does the green checkmark mean?
The green checkmark highlights the "best" card for each numeric dimension — highest raw value, highest gem value, highest grade multiplier, oldest card, and rookie status. For text dimensions like Sport and Set, no winner is marked since these are categorical.
What is the Grade Multiplier?
The Grade Multiplier shows how much more a card is worth in gem mint condition compared to raw. A 10x multiplier means the PSA 10 value is 10 times the raw value. Higher multipliers indicate cards where grading creates the most value — these are the best candidates for grading submission.
Can I compare cards from different sports?
Yes! Cross-sport comparison is fully supported. This is useful for portfolio diversification decisions — comparing a baseball rookie card against a football or basketball card to see which offers better value or growth potential.
