Juan Valera

As of November 4, 2026, Prospect Card Radar does not have enough verified data to call Juan Valera’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 83rd percentile of 119 tracked prospect pitchers (2.14 FIP over 9.3 innings at High-A), measured November 3, 2026. There is no confirmed sold comp for his base 1st auto right now, so the only price here is an asking price. 4 Bowman Chrome listings are live on eBay, asking $3 to $70 (average $23). 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.

No base 1st Bowman Chrome autograph for Juan Valera is listed on eBay right now, so there is no base-auto asking average to quote. The live listings are Bowman Chrome · variants only (no base 1st auto active), averaging $23 — a different card with its own price point, not the base auto. Prospect Card Radar re-checks multiple times per day.

Juan Valera is ranked #123 in the Prospect Card Radar composite top 300, which blends MLB Pipeline, Fangraphs, and Baseball America rankings (composite last recomputed September 19, 2026). Individual source ranks are listed at the top of his prospect page.
