Every figure in this table is an asking price: the average of what sellers currently want across live eBay listings, base autos only. It is not what the card last sold for — where we have a verified sold comp it is shown above, tagged sold. Numbered parallels, refractor colors, superfractors, and printing plates are excluded so the numbers stay apples-to-apples across product lines. Refreshed multiple times per day.
| Card type | Avg asking | Asking range | Raw listings | PSA 10 asking |

Higher = better. 50th is league median, 90th+ is elite. The orange Card Market bar shows where the price ranks — not whether it’s a good buy.
