Collection Health Score

The score evaluates your collection across 5 dimensions: Diversification (sport/era/player spread), Grade Quality (average condition and graded percentage), Risk Exposure (concentration in volatile assets), Growth Potential (rookie cards, trending players, modern sets), and Liquidity (how easily you could sell your collection). Each dimension scores 0-20, combining for a 0-100 total.

Add cards manually by specifying the sport, era, estimated value, condition (raw or graded with grade), and card type (rookie, base, insert, auto). You can add as many cards as you want. The tool also offers 5 preset collection profiles if you want to see example scores for common collector types.

Scores above 80 are considered Excellent — well-diversified, high-quality, liquid collections. Scores 60-79 are Good with room for improvement. Scores 40-59 indicate moderate risk areas. Below 40 suggests significant concentration risk or quality issues. Most casual collectors score between 50-70.

The tool provides specific recommendations based on your weakest dimensions. Common improvements include: diversifying across sports and eras, getting key cards graded, reducing concentration in a single player, adding rookie cards for growth potential, and ensuring you have liquid assets that sell quickly on eBay.
