Cards that feel like cards

Tilt one with your mouse or finger. Light follows you across the surface, and foil only appears when a card’s rarity calls for it. Tap to flip.

A calculator that shows the whole picture

Most grading math only looks at the 10. Real submissions come back as 9s and 8s too, so the Grading Lab weighs every grade by how likely you think it is.

  • Your numbers, not ours. You enter prices you’ve checked yourself. We never invent market values.
  • Every outcome. See profit or loss at each grade and your chance of losing money.
  • The honest alternative. We compare grading against just selling the card raw.
Worked example

One card, every outcome

A made-up card with example numbers, run through the same calculator the Grading Lab uses. It isn’t market data or a prediction.

Assumptions

  • Paid $40.00; sells raw for $40.00
  • Grading $25.00 + shipping and insurance $10.00 = $35.00
  • Selling fees 13% + $0.40 per sale + $5.00 shipping to the buyer
  • Grade chances and sale prices are example inputs; in the Lab you enter your own

  • Expected result across your grade chances: −$8.19 after grading costs and selling fees.
  • It makes money at Gem Mint 10 or better, which you give a 25% chance.
  • Break-even sale price: $92.41.
  • That's $2.41 better than selling it raw (−$10.60).

“Expected” is an average across the example chances, not a promise: a single card gets one grade.
