How It Works

The Market Lists It

Live card listings are pulled nightly from major marketplaces — prices, grades, sellers, and card details.

We Score It

Our scoring engine compares each listing to 90 days of sold comps for that exact card and grade. The result: a 0–100 deal score.

You Know If It's a Deal

Grand Slam (80+): buy with confidence. Extra Base Hit (50–79): solid deal. Strikeout (0–49): walk away.
