Estimate, recent sales and range: adjusted to typical eBay auction prices.
How we got this
Fewer than 5 sales we counted in 90 days and too little related data for a modeled figure, so this is the plausibility-weighted median of this grade's own 11 sales in the last 365 days, each moved to today by how this era's prices have changed since it sold. A sale far from the others counts for less.
Recent sales: the middle (median) of the last 3 sales we counted (Aug 27 to Oct 7), 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 2,764 estimate-to-next-sale pairs for grades with fewer than 5 sales in 90 days, Diamond & Pearl to HGSS, from Jan 1, 2025 to Oct 15, 2026: half the next sales landed within 25 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 22 percent on 44,262 past cases (Jan 1, 2025 to Oct 16, 2026).
Sales in the last 90 days ran from $536.00 (Aug 27) to $1,025 (Oct 7) (4 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.
An estimate from completed sales. Not an offer or an appraisal.

About this chart
Log scale: the highest sale is more than 4 times the lowest, so equal steps on the price axis are equal percentage changes.
Buy It Now and auction-house prices are moved by the gap we measure between venues in this era, so every dot is comparable with an eBay auction. Tap a dot to see the price paid.

Grades
Grades 8 to 8.5 share one estimate so a lower grade never shows above a higher one.
Grades 7 to 7.5 share one estimate so a lower grade never shows above a higher one.
Grades 3 to 4 share one estimate so a lower grade never shows above a higher one.
Grades 1 to 2 share one estimate. Their recent sales overlap, so we do not rank them apart.
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.
