A full estimate: 9 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 7 (2 sales since). It stays at limited evidence until 5 sales since.

This grade's own figure was $1,025, 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 (1.86, set (5 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 20 to Oct 14), 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.

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 $255.00 (Aug 22) to $1,200 (Oct 14) (9 sales, prices paid).
