Card Combo Analyzer

The Card Combo Analyzer lets you build a multi-card package (2-10 cards) and get instant analysis including total raw and gem-mint value, diversification score, grading upside potential, trade package rating, and personalized improvement suggestions. It helps you build the most appealing trade packages.

The trade rating considers total value and card count. Premium Package requires $1,000+ across 3+ cards. Strong Package needs $500+ total value. Decent Package needs $100+. Quality Cards means fewer but higher-value cards (avg $50+). Budget Package is anything below these thresholds.

The diversification score (0-100) measures four factors equally: sport variety (are you spread across baseball, basketball, football, hockey?), player uniqueness (different players vs duplicates), era coverage (vintage through ultra-modern), and rookie/veteran mix. Higher scores mean more appealing packages for trade partners.

Grading upside shows the difference between raw card values and gem-mint (PSA 10) values in your package. A high multiplier means your cards gain significantly more value when graded. The total upside shows the dollar amount you could gain by grading all cards to gem-mint condition.
