Grading Flip Finder
Find raw cards with the best PSA 10 and CGC 10 flip spreads. Sort by multiplier, filter by liquidity, and check gem rates — the real-world probability of a 10 — before you spend a dime on submissions.
Grading Spread
PSA 10 and CGC 10 prices vs. raw 30-day median. The dollar gap between what a card costs raw and what it sells for graded.
Gem Rate
The percentage of graded copies that hit a 10. Population-based probability from real pop report data — not a guess.

67% gem rate means 2 out of 3 submissions hit PSA 10. At a $561 spread per hit, the expected value is strongly positive — and the scanner surfaces this in seconds.
Scanned across 36k+ tracked Pokemon TCG cards, surfacing the ones with real grading signal data. The table does the heavy lifting — you sort, filter, and act.
One bad submission costs more than a year of Master. A single PSA 10 on a $5 raw card can return $40–$200+ at auction.
