Core functions
Built around the card research workflow.
Market value lookup
Review recent comparable sales and estimated value ranges before buying, selling, trading, or grading.
Condition-aware notes
Record condition details, visible flaws, and grading assumptions so price estimates stay grounded.
Collection tracking
Save scanned cards, organize owned inventory, and monitor cards that may deserve deeper research.
Research checklist
Use clear prompts for verifying variants, serial numbers, autographs, memorabilia, and grading labels.
Exportable records
Keep structured card notes that are easier to share with buyers, sellers, shops, or insurance records.
Trust through clarity
Useful for research, honest about limits.
Sports card prices depend on condition, grade, scarcity, timing, and buyer demand. CardsKnow is designed to speed up research, not replace expert authentication or formal appraisal.
- CardsKnow is not a formal appraisal service.
- Very rare cards, damaged cards, altered cards, and low-volume markets may require manual research.
- Estimated values depend on available comparable sales and may change quickly.
- The app helps with research but does not guarantee selling price, authenticity, or grading outcome.
