Every figure on this page is an observed number. Raw prices come from TCGplayer; graded medians are completed eBay sales, shown with the sale count behind each one. We don't estimate, model, or fill in gaps — if a grade has no sales on record, it isn't listed. Grading outcomes are not guaranteed: most raw cards do not come back a 10, which is exactly why the 9-grade number is on this page. Where PriceCharting has no PSA-9-only figure we show its pooled 9 — PSA, BGS, CGC and SGC together — and label it as such rather than call it a PSA 9.
