Estimate, recent sales and range: adjusted to typical eBay auction prices.
How we got this
A full estimate: 6 sales we counted in the last 90 days, weighted toward the most recent.
Recent sales: the middle (median) of the last 3 sales we counted (Aug 16 to Oct 4), 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 4,823 estimate-to-next-sale pairs for grades with 5 to 8 sales in 90 days, EX era, from Jan 1, 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 $390.00 (Sep 5) to $710.00 (Oct 4) (6 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 · Holo
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.
