What the evidence says
The latest recorded PSA 9 sale ($199 on Nov 1, 2026) sits 102.8% above the $98 fair value, too far off to read as this grade's price. The value rests on 11 recorded PSA 9 sales. The latest sale ran above the recent run: the last 4 PSA 9 sales averaged $96, within 2.3% of the value. Its confidence band runs from $87 to $109. A PSA 10 ($1,004) is worth 10.3 times a PSA 9 ($98). With limited sales evidence, read the gap and the band as rough guides.
