| Percentile vs. | ||||
|---|---|---|---|---|
| Metric | Value | Set | Era | All |
| Value / CopyPSA 10 price divided by how many PSA 10 copies exist. Roughly: how much value rides on each perfect copy. | $0.7445 | 33 | 7 | 23 |
| Gem RateOf every copy PSA has ever graded, the share that came back a perfect 10. | 23.3% | 32 | 37 | 42 |
| Gem Premium (10:9)How much more a PSA 10 costs than a PSA 9 of this card. 2.5× means the perfect copy sells for 2.5 times the near-perfect one. | 5.2× | 57 | 44 | 37 |
| Vs ExpectedThis card's price vs what you'd expect for a card with its PSA 10 population in its era. 9× means the market pays nine times what rarity alone explains — collector demand. Below 1× means it's cheaper than its scarcity suggests. | 0.7× | 55 | 55 | 51 |
