There are several relevant shared factors among the top sports cards sold that can help predict which cards are going to be profitable.
Sports Card Predictive Investment Factors
- Greater than 70% of the top sports cards sold are generally rookie cards
- The number of championships won and MVPs held are the two most important predictors driving sports card value
- The higher the number of championships, the larger increases in sports card value
This information is based on a recent research study backing up these sports card predictive metrics.
Another highly intangible predictive factor is a player’s popularity. This includes fans, peers, and the media. A player’s popularity can be measured via their search popularity score (SPS) and can be interpreted via Google trends and Qscore.
