The biggest driver of value is simple: who is on the card?

Cards featuring:

  • Superstars
  • Hall of Famers
  • Top rookies

…will almost always be more valuable.

More fans = more demand = higher value.

The rarer the card, the more valuable it can be.

Look for:

  • 1/1 cards
  • Low serial numbers (/5, /10, /25)
  • Short prints (SP, SSP)
  • Rare parallels (Gold, Superfractor, etc.)

Fewer cards = more competition among buyers.
