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.
As of September 20, 2026, Prospect Card Radar does not have enough verified data to call River Ryan’s 1st Bowman Chrome auto overpriced or underpriced. His base 1st Bowman Chrome auto does not have an established card market yet, so there is no price percentile to compare his on-field performance against. What we can say: his arm ranks in the 74th percentile of 124 tracked prospect pitchers (3.08 FIP over 40.3 innings at Triple-A), measured September 19, 2026. There is no confirmed sold comp for his base 1st auto right now, so the only price here is an asking price. 26 Bowman Chrome listings are live on eBay, asking $42 to $2,250 (average $218). A verdict is published only once on-field percentiles and a price we can stand behind are both available, so this page will carry one as soon as that data lands.
