Key Metrics · Grading Activity
| 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. | $12 | 55 | 69 | 73 |
| Gem RateOf every copy PSA has ever graded, the share that came back a perfect 10. | 17.9% | 35 | 51 | 53 |
| 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. | 7.2× | 64 | 69 | 59 |
| 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. | 0.9× | 76 | 60 | 60 |
