Estimated from similar cards: fewer than 5 sales we counted in 90 days, so the figure is modeled from 2 sales in 90 days, PSA 5 and PSA 3 prices.

This grade's own figure was $53, out of order with PSA 3. Its own sales conflict with the grade below, so the estimate is PSA 3 times the typical ratio between the two grades (1.00, era and price tier (5 cards)), limited to 3 times its own figure and 1.5 times its highest sale we counted in three years.

Estimates with limited evidence had a median error of 22 percent on 44,262 past cases (Jan 1, 2025 to Oct 16, 2026).
