eBay sold listings by grade, last 90 days.
Data through Jul 9, 2026.
Based on a raw cost of $42.69 (Near Mint) and the median of recent eBay sales at each grade. Each figure is what you'd net after grading and selling — the grading fee, a $15.00 shipping estimate, and a 12.9% sale fee are already subtracted. It doesn't predict the grade your card will get; it shows what each outcome is worth so you can decide.
