What the evidence says

The latest recorded PSA 10 sale ($11 on Nov 18, 2025) sits 90.0% below the $105 fair value, too far off to read as this grade's price. The value rests on 3 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 $84 to $125. A PSA 10 ($105) is worth 3.2 times a PSA 9 ($33). Over the past 30 days the PSA 10 value has fallen 0.6%. With sparse sales evidence, read the gap and the band as rough guides.
