What the evidence says

The latest recorded PSA 9 sale ($45 on Oct 28, 2026) sits 69.7% above the $27 fair value, too far off to read as this grade's price. The value weighs 1 PSA 9 sale from the past year, not the latest one alone. With so few PSA 9 sales on record, a single sale can sit far from the value. Its confidence band runs from $20 to $33. A PSA 10 ($121) is worth 4.5 times a PSA 9 ($27). Over the past 30 days the PSA 9 value has risen 181.9%.
