What the evidence says

The latest recorded PSA 10 sale ($85 on Apr 5, 2026) sits 202.7% above the $28 fair value, too far off to read as this grade's price. The value rests on 2 recorded PSA 10 sales. With so few PSA 10 sales on record, a single sale can sit far from the value. Its confidence band runs from $25 to $31. A PSA 10 ($28) is worth 1.9 times a PSA 9 ($15). Over the past 30 days the PSA 10 value has risen 31.3%. With sparse sales evidence, read the gap and the band as rough guides.
