About graded prices
Graded values are Pokémon Price Tracker’s eBay estimates for the product, not a verified match to the selected printing. The current supplier smart estimate is used when available and not flagged as an outlier; otherwise we use its reported median. Graded charts show historical daily sale averages, which differ from the current smart estimate. Sparse or old sales can make these estimates uncertain.
