Ramon Marquez has no Bowman Chrome 1st autograph listed or sold right now, so there is nothing to price yet. This page fills in on its own as soon as one appears.
Nothing here is an estimate. A price appears only once a real Bowman Chrome 1st auto for him lists or sells.
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 Ramon Marquez’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 90th percentile of 124 tracked prospect pitchers (2.56 FIP over 69.0 innings across A+/A), measured September 19, 2026. 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.
Ramon Marquez is ranked #93 in the Prospect Card Radar composite top 300, which blends MLB Pipeline, Fangraphs, and Baseball America rankings. Individual source ranks are listed at the top of his prospect page.
Ramon Marquez plays P in the Giants organization.
