Cards whose grading arbitrage is eroding fastest — read straight from population trends, so it works even before sale prices come in. A high score means the graded supply is surging, the surge is speeding up, or fresh copies are grading to a 10 faster than the card's history — all of which shrink the raw→graded edge. Pair it with the Flip Board: if a card is a good flip and high here, move now; if it's high here but not yet a flip, the window has likely already closed.
| Card | Edge-closing score | Graded supply (30d) | Trend | Gem rate — new vs lifetime | Graded pop | Raw price |
|---|
Score blends supply velocity (30-day pop growth), acceleration (recent growth vs the long-run rate), and gem pressure (recent submissions' gem rate vs the card's lifetime rate). Higher = the edge is closing faster.
