Prices Are Estimates

Last updated October 17, 2026

Every value in LockBox is an estimate based on recent sold prices for the same card. It is not an appraisal, a guarantee, or an offer to buy or sell.

Why values can be off

  • Prices come from past sales. The market can move fast after a big game, trade or injury.
  • Condition, centering, grade, parallel and serial number all change value — and photos or details can be misread.
  • Rare cards, like 1 of 1s, may have few or no recent sales.
  • Price sources can be delayed, incomplete or temporarily unavailable.

When we show N/A

If we can't find a reliable sale for the exact card, or its last known sale was more than 18 months ago, we show N/A with a red border instead of guessing.

Before you trade or sell
