Frequently Asked Questions
What does the heat score measure?+
The heat score (0-100) measures how "hot" a card is right now based on 5 factors: rookie status (rookies command premiums), recency (newer cards have more active demand), grade premium (high gem multipliers signal grading opportunity), value tier (higher-value cards attract more collector interest), and seasonal timing (in-season sports have higher demand).
What should I do with a high heat score card?+
Cards scoring 75+ are at peak demand — consider selling if you want to maximize value. Cards at 55-74 are in a good position — hold and watch for catalysts (player performance, awards, trades) that could push them higher. Cards below 40 are cooling off — they may be buy opportunities if the player has long-term potential.
How does seasonal timing affect heat score?+
Each sport has demand cycles. Baseball cards peak March-June (spring training through the first half). Football peaks August-February (preseason through playoffs). Basketball follows October-April. Hockey follows October-June. Off-season cards lose 5-10 heat points.
Can I analyze my entire collection?+
Yes! Add as many cards as you want. The tool calculates an overall collection heat score (average of all cards) and shows individual scores for each card. This helps you identify which cards to prioritize selling and which to continue holding.
Is the heat score the same as market value?+
No. A high heat score means a card is in a favorable position to sell NOW — not necessarily that it is the most valuable. A $10 rookie card in-season might score higher than a $500 vintage card in the off-season because the rookie has more immediate demand drivers.
