Estimate, recent sales and range: adjusted to typical eBay auction prices.
How we got this
A full estimate: 14 sales we counted in the last 90 days, weighted toward the most recent.
Recent sales broke from the earlier level, so the estimate restarted from them on Oct 12 (2 sales since). It stays at limited evidence until 5 sales since.
This grade's own figure was $2,893, out of order with the other grades. Its own sales conflict with the grade below, so the estimate is the other grades times the typical ratio between the two grades (1.82, set (6 cards)), limited to 3 times its own figure and 1.5 times its highest sale we counted in three years.
Recent sales: the middle (median) of the last 3 sales we counted (Sep 18 to Oct 12), each adjusted to typical eBay auction prices: Buy It Now and auction-house prices are moved by the gap we measure between venues in this era. The sales list shows the prices paid.
Checked on 6,264 estimate-to-next-sale pairs for grades with 9 or more sales in 90 days, EX era, from Jan 2, 2025 to Oct 16, 2026: half the next sales landed within 15 percent of the estimate at the time (as of Oct 18). A record of past estimates, not a guarantee for this card.
Estimates with limited evidence had a median error of 20 percent on 25,291 past cases (Jan 1, 2025 to Oct 16, 2026).
Sales in the last 90 days ran from $700.00 (Jul 24) to $3,500 (Oct 12) (14 sales, prices paid).
Evidence: strong means at least 4.5 effective recent sales (older and clustered sales count for less) with a spread under 0.15; moderate, at least 2.8 with a spread under 0.30; limited, anything less. The basis (sales of this grade, or estimated from similar cards) is stated separately.

Grades
Grades 2 to 3 share one estimate. Their recent sales overlap, so we do not rank them apart.
PSA 8 is estimated from the set's grade ratios because its own sales conflict with the other grades.
PSA 7 is estimated from the set's grade ratios because its own sales conflict with the other grades.
Our estimate for each grade, with the change over 30 days and how much evidence backs it. Grades with few recent sales show the range of what sold instead.
How we got this
A grade's estimate needs 5 or more sales we counted in 90 days; otherwise the panel shows the lowest to highest sale of the last year. When neighbouring grades' sales overlap, or a lower grade's figure would sit above a higher grade's, they share one precision-weighted estimate (each figure weighted by how tight its range is). The 30-day change compares with the last settled estimate and shows only with strong or moderate evidence.
